<blockquote>“For a new product to be successful, it is not enough for it to work—almost everything around us works quite well. The design matters.”</blockquote>This is what Iván Arakistain, a technologist and researcher at Tecnalia said. After winning the Connect for Good challenge, we interviewed Arakistain to discuss his award-winning project on sustainable logistics infrastructure and his insights into the logistics industry, particularly that of perishable goods.Logistics is a dynamic field fraught with challenges, and sustainability is a growing concern, particularly in transporting perishable goods. Iván Arakistain, representing Tecnalia, won first place in the Connect for Good challenge with an innovative concept that leverages a low-power IoT solution to monitor and enable eco-friendly transport of perishable goods.The&nbsp;<a href="https://www.wevolver.com/article/connect-for-good-low-power-wireless-sustainability-challenge" target="_blank">Connect for Good Challenge</a> is a joint initiative by Nordic Semiconductor, Mouser Electronics, Soracom, and Crowd Supply aimed at fostering innovation for social and environmental good. It brought together a worldwide network of engineers, entrepreneurs, and developers around one mission: “to devise low-power wireless solutions that contribute towards achieving the United Nations Sustainable Development Goals.”&nbsp;Arakistain's winning project is a game-changer in sustainable logistics. Through advanced monitoring and anomaly detection, this innovative solution optimizes the transport of perishable goods while eliminating the need for energy-intensive refrigerated cargo trailers. Thus, it significantly reduces carbon emissions and operational costs while ensuring the integrity of the cold chain. Through the integration of IoT technology, including low-energy sensors and GPS and coupled with mini solar panels for autonomy, the project sets a new standard for eco-friendly transport in the logistics industry, with broad implications for global sustainability efforts. The key component of this project is the integration of the&nbsp;<a href="https://www.wevolver.com/specs/nrf9160-development-kit" target="_blank">nRF9160 Development Kit</a>, chosen specifically for its low energy consumption and reliable cellular connectivity.In this exclusive interview, Arakistain sheds light on his journey, the inspiration behind his project, and the impact he envisions on the logistics industry's future.<h2 dir="ltr">Interview with Iván Arakistain of Tecnalia</h2><h3 dir="ltr">Can you briefly describe your winning project and the main problem it addresses in the logistics industry?</h3>One of the main challenges of the logistics industry is the sustainable transport transition. This focuses on decarbonizing the transport industry, especially because today, at least in Spain, it’s heavily based on trucks; most of the logistics happen on the road, and trucks consume a lot of fuel. So, we have to shift from that to a cleaner way of transport.Some years ago, we had a customer who sold precooked food.&nbsp;They mentioned something to us that sparked this idea process: If they could deliver the food in one day from their factory to the end customer, they would be able to avoid refrigerated transportation, especially since it’s relatively expensive, requires a lot of fuel, and is very complex.So, we started exploring that. At that time, the technology was not quite ready for the application, mainly for areas like the south of Spain, where it's very hot in the summer. The logistics were not as fast as today, but as things have evolved, we are now able to transport food—or perishable goods—in proper condition to the end customer in a short a time as needed so it arrives safely.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1713160590293-0_Ivan+Arakistain.jpg" style="width: 100%px;" class="fr-fic fr-dib"><h3 dir="ltr">What inspired you to focus on developing a more sustainable method for transporting perishable goods?</h3>Well, the main goal is to deliver goods fast and with as low carbon emissions as possible. For that, we must change from only using transport by trucks to combining truck and train, which is obviously much cleaner environmentally. By doing so we can ensure more availability, lower cost per kilometer, and a smaller cargo footprint.&nbsp;Let’s look at how your project aligns with the Sustainability Development Goals. Could you tell us how your solution targets these goals?Our solution’s practical implications impact goals 7 (Affordable and Clean Energy), 11 (Sustainable Cities and Communities), and 13 (Climate Action). We are very focused on energy efficiency and sustainability goals for cities and districts. Our application can help reduce the cargo footprint and accelerate the transition from the current fuel-based transport to a more electrified way of transport.&nbsp;Of course, we cannot transition directly from 0 to 100%, so we must ensure the transition is smooth. In our area of focus, the technology background is in artificial intelligence for microcontrollers and small devices. We embed this intelligence into the embedded device so that we can know via our electronic sensors if the transported food is in good condition. We can also sense whether any volatile compounds can impact the condition of the food.By making those changes, we estimate that up to 10% of carbon reduction is possible. And that also applies to energy consumption, even though I’m not sure if it’s a linear relationship. However, the estimation stands.<h3 dir="ltr">Let's move onto the technical side. How does your solution work? Is embedded AI the differentiator from traditional energy-intensive refrigeration?</h3>As I said, we are focused on AI for microcontrollers. So, first, we develop the AI models in servers and powerful computers. Then, we reduce those models so that they can run in a small controller with a few kilobytes or a small RAM. For this application, we are focused on two types of inference.The first type of inference is air quality to determine the state of the product. The second inference type is AI for vibration analysis, which is something we have implemented here and in other projects. In this case, we can analyze if the vibration of products in the truck matches the orientation to make sure everything is good. In other cases, we also do this AI analysis of vibration for structural health and many other applications.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1713160621737-1_Manufactured+PCB+Top.jpg" style="width: 100%px;" class="fr-fic fr-dib"><h3 dir="ltr">How accurate and precise are the AI model results in a real-world application?&nbsp;</h3>There are two processes that we do. First, we collect all the data, and then we perform model training and model testing on our computers. We split the data set into two parts: about 80% of the data is used for training the model, and the remaining 20% or so is used for testing the model.In our computer simulation, the results were very good; you can get up to 96% accuracy. But we both know that’s not the reality. Getting a very high score virtually means the model is quite good. However, when you go into the real world and flash the firmware into the microcontroller you’re using in the actual sensor, the accuracy decreases a bit. Still, we can get good enough accuracy with this model.Were there any particular challenges you faced in the development process, and how did you overcome them?As I said earlier, the original idea came some years ago with this customer we were working with. They produced precooked food, and we did some real testing with them. We sent the food with a trucker and other things to actual customers. At that moment, we realized that the technology was not quite ready, not because of the electronics but because of the isolation and insulation challenges. For that, you’d need excellent isolating materials so that temperatures are kept in the correct range.&nbsp;This was about eight to nine years ago. At that point, we did develop a complete solution, and we knew the idea was good, but it was not quite ready because of the isolation challenge. Since then, we have kept thinking and working on it, and now we know that it is a feasible application, especially since there are much more efficient containers for food transport than years ago. There are better isolation materials, which helped this improve.<h3 dir="ltr">Looking into the next decade, what are the biggest hurdles in scaling and implementing your solution across different regions and logistics networks?</h3>The main difficulty is the limited time for delivery: It has to be done within the first 24 to 48 hours and the products need a low temperature range.Of course, I think it's scalable. Still, one of the biggest challenges is the container. We need to use special containers with good insulation for this. Basically, once we are able to prove to customers that they are going to save so much on each transportation, then it makes sense.So far, we have tested with first-class precooked food, which is already prepared and ready for eating upon reheating in a restaurant or somewhere else. We are not so focused on uncooked food.<h3 dir="ltr">Let’s dive a bit into the economic side of things. What are the economic benefits of your solution for logistics companies and end users?</h3>The economic benefits mainly rely on the use of nonrefrigerated transportation. As a result, you can save about 10% of the transportation cost. It consumes less fuel and energy. It's simply more efficient. We are also very interested in combining ways of transportation: using not only trucks but also trains. Here in Spain, we have quite a robust train infrastructure, but nowadays, it is more focused on passengers than goods. So, I think we must leverage the train infrastructure and combine it with trucks in the future.Also, for international shipments, combining the truck with the train is important so that the driver does not need to drive so far. The truck driver would simply mount the truck with the goods from a train carriage, move onto another carriage to collect goods from there, and then deliver them locally.This is a standard logistics process. We are simply using the existing infrastructure. The only additional requirement would be the special containers for the food that I mentioned earlier.<h3 dir="ltr">You mentioned one customer already.&nbsp;Have you discussed this with other members of your target market? How have your target customers responded to your solution so far?</h3>Yes. 15 days ago, I was at a logistics and transportation fair in Bilbao. I gave a speech there and talked to potential customers. Clearly, there is some potential, but of course, we need to keep the focus on the end customer.<h3 dir="ltr">By focusing on the end customer, what strategies are you employing to encourage the adoption of your technology within the market?&nbsp;</h3>In Tecnalia, we work with different approaches to ensure the technology adoption. We identify and manage deep-tech business opportunities, through a venture building process to accelerate their industrial commercialization. We create new startups or commercialize licenses, accelerating the incubation of technological assets until they are turned into investment opportunities capable of generating economic and social value.&nbsp;<h3 dir="ltr">How do you see your solution evolving in the next five years?</h3>I think that it has quite a lot of potential. We are still in a transition stage, where not everything is well-defined. The path is clear: we have to shift to the electrification of transport. But the speed at which this is going to happen is yet to be clear. Yet, I think that it has significant potential for the future because logistics is a fast-growing sector.<h3 dir="ltr">Is there close competition to your technology from bigger companies already established in the logistics market?</h3>Yes, there is. For example, some years ago, big companies like Amazon tried to sell perishable food to end customers in a very short time. However, they were not very successful because it’s not easy to deliver that fast in a cost-efficient way.Our case is a little different. It focuses on precooked food for industrial partners. The customer I mentioned earlier is not selling to end customers but rather to restaurants and other businesses. So yes, there are big players, but they are not entirely in the same market niche as ours.<h3 dir="ltr">Are there other applications or industries where your technology could be applied beyond the niche cold chain logistics?</h3>Yes, we use embedded AI for structural health monitoring in various cases. Here, you would need to know the condition of a structure. In Tecnalia, for example, we have some dedicated lab equipment, such as sensitive accelerometers. But the cost of such devices is typically quite high. They are not devices you can leave on a structure but rather devices you use within a specific timeframe.So, we are developing small, affordable devices that can use MEMS accelerometers, inexpensive microcontrollers, and embedded AI to provide early warnings if there is an anomaly, failure, or any other event on which the model is trained.The new devices we are developing would cost as much as an order of magnitude less than the typical measuring and monitoring equipment. They would only provide an early warning, after which the experts could go and perform more extensive measurement and testing.Another example of our embedded AI would be audio detection. Consider a large dataset of street sounds that can take over six gigabytes – that is a lot of information. For this, it's possible to train an AI model that takes no more than kilobytes – which is significantly less – and embed it into a microcontroller to classify the sounds. We tested this, and the model was able to accurately identify and classify the sounds of a car horn, for example, a dog barking or children playing. This is a solution to tackle problems with lots of data using a compressed model that can accurately classify the data without requiring so much power.<h3 dir="ltr">Going back to the project experience, what have you learned from working on this project that you think is crucial for innovation in sustainable technologies?</h3>At Tecnalia, we are experts in many different fields. The most interesting thing about working in an applied research and technological development centre like Tecnalia is that I can collaborate with experts in multiple fields, such as electronics, logistics, structures, and energy efficiency. For such projects to work, I have to work with lots of people to solve the problem.&nbsp;Also, experts in AI are not all the same. Some of them are more focused on big processors like NVidia devices, and we need to collaborate with them to understand the models and be able to quantize and reduce the models down to the microcontroller level.What advice would you give to other entrepreneurs or innovators looking to make a difference in the green technology space?&nbsp;My advice would be to prototype as much as they can. In electronics, we are quite used to prototyping fast. That's a good thing for our sector. But in other areas, it might be more difficult to prototype. I would also encourage people to collaborate with other experts and learn from them.<h2 dir="ltr">Conclusion</h2>Iván Arakistain's winning project exemplifies the potential for low-power IoT solutions to revolutionize the transportation of perishable goods. By leveraging advanced monitoring and anomaly detection, Arakistain's project offers a promising avenue for reducing carbon emissions and operational costs while maintaining the integrity of the cold chain.&nbsp;As we look to the future, the scalability and adoption of such solutions present ongoing challenges. Yet the momentum generated by initiatives like the Connect for Good Challenge signals a promising trajectory towards more innovation and sustainable solutions and systems.

Revolutionizing Pipeline Inspection: The Power of the ROCK 3 Compute Module

Three-and-a-half&nbsp;years on from the Bluetooth Special Interest Group’s (SIG) announcement of a new specification that defined a high quality, low-power audio codec (Low Complexity Communications Codec or LC3) that promised to redefine audio streaming and wireless sound,&nbsp;<a href="https://www.nordicsemi.com/Products/Wireless/Bluetooth-LE-Audio" target="_blank" rel="noreferrer noopener">Bluetooth LE Audio</a>&nbsp;(LE Audio) is finally about to hit the commercial mainstream.The delay has due to the development time needed to shake out the bugs from what is a complex technology. As Chuck Sabin, Senior Director, Market Development at the SIG says, developing specifications is hard, particularly when there are billions of Bluetooth-enabled receiving devices out there. That’s a lot of interested parties invested in ensuring the specification is going to deliver so things work perfectly.&nbsp;With the due diligence now complete, and a year on from the adoption of the specification, the first commercial implementations of LE Audio are now coming to market. Within another three or four years, Sabin predicts—once the tech is natively adopted by iOS and Android smartphones and major wireless audio device vendors—LE Audio will be universal.&nbsp;&nbsp;When it is, wireless audio will become unrecognizable from anything we’ve previously experienced, and not just for the millions of us that use wireless headphones and earbuds, but more importantly for the hearing impaired as well.&nbsp;&nbsp;<h2>True Wireless Stereo&nbsp;and&nbsp;better battery life&nbsp;</h2>Two key advantages of LE Audio over Classic Audio that will drive mass consumer adoption are the noticeable improvements in audio quality and longer playtime.&nbsp;&nbsp;While Bluetooth LE supports multiple communication topologies for data transfer (for example, Bluetooth Mesh), it only supports point-to-point communication for audio streaming. LE Audio’s multi-stream audio functionality however enables multiple devices—for example a pair of earbuds—to receive their own unique audio stream. The left and right channels retain the original precise musical timing upon replay. The result is excellent stereo sound together with long battery life. That’s unlike the earbuds in use today that can only stream audio to a single device and therefore require an engineering work around to retransmit the second channel to a second earbud, at the cost of battery life.&nbsp;On the question of battery life, quantifying the expected reduction in power consumption over Classic Audio is difficult because it will depend on both implementation and product use. Product developers focused on providing the highest audio quality might choose to implement the LC3 codec for hi-fidelity rather than aiming for significant gains in playback time. Others may choose to focus entirely on extending battery life by trading-off sound quality. In the latter case, the battery life of your earbuds or Bluetooth speaker could double.&nbsp;<h2>Auracast&nbsp;broadcast audio promotes&nbsp;inclusion&nbsp;</h2>Another breakthrough feature of LE Audio is the addition of Auracast broadcast audio. Auracast allows an audio source device such as a smartphone, laptop, TV, or sound system to broadcast one or several audio streams to an unlimited number of Bluetooth audio receivers.&nbsp;&nbsp;There are several potential use cases for Auracast, but chief among them is the ability for it to become a high quality, lower cost augmented and assistive listening technology in venues where PA or hearing loop infrastructure is currently deployed. Such a use case opens up wider accessibility for the over 1.5 billion people living with hearing loss around the world. It can also enable multi-language audio streams in locations that support simultaneous translation services.&nbsp;&nbsp;<h2>Next gen SoCs&nbsp;optimized for LE Audio&nbsp;</h2>While LE Audio’s LC3 codec does demand more computational resource than Classic Audio’s SBC codec to compress and decompress audio, the latest generation of wireless SoCs can comfortably meet this requirement without compromising any power consumption advantages. For example, Nordic Semiconductor’s&nbsp;<a href="https://www.nordicsemi.com/Products/nRF5340" target="_blank">nRF5340</a> SoC features a dedicated Arm Cortex-M33 application processor, optimized for performance and with ample overhead to look after the computational demands of advanced audio codecs. The SoC incorporates a second M33 processor to supervise wireless connectivity and which is optimized for low power consumption.&nbsp;Looking forward to mass commercialization of LE Audio, Nordic’s fourth generation of wireless SoCs, the&nbsp;<a href="https://www.nordicsemi.com/Products/nRF54L15" target="_blank">nRF54L15</a>&nbsp;and&nbsp;<a href="https://www.nordicsemi.com/Products/nRF54H20" target="_blank">nRF54H20</a>&nbsp;are both now sampling, and represent the future of not just LE Audio, but for many applications demanding complex machine learning (ML) and support for sensor fusion at the edge. The&nbsp;nRF54H20 SoC features multiple Arm Cortex-M33 processors and multiple RISC-V coprocessors optimized for specific types of workloads. The level of integration this will provide product developers ensures tomorrow’s LE Audio solutions—from earbuds to hearing aids—will consume even less energy, be smaller, and simpler to bring to market.&nbsp;<h2>LE Audio and&nbsp;Auracast&nbsp;world first&nbsp;</h2>The first commercialized LE Audio solutions are already available. Earlier this year, global hearing technology solutions provider GN launched a&nbsp;<a href="https://www.nordicsemi.com/Nordic-news/2024/01/GN-Group-unveils-Nordic-powered-Bluetooth-LE-Audio-and-Auracast-broadcast-audio-TV-streamer" target="_blank">world first LE Audio and Auracast broadcast audio TV streamer</a>, enabling people suffering from hearing loss to stream hi-fidelity audio between their television and their hearing aids, with all the benefits of Auracast. Working seamlessly with the company’s new ReSound Nexia hearing aids or other LE Audio compatible solutions, the TV-Streamer+ integrates a Nordic’s LE Audio- and Auracast-capable SoC to deliver low power, low latency, and long range wireless connectivity with improved audio quality.&nbsp;&nbsp;For people with hearing loss the launch means they can enjoy immediate speech clarity at their preferred volume, while at the same time enjoying the benefits of Auracast. For developers and consumers, it means the LE Audio and Auracast are in the public eye.&nbsp;

Three-and-a-half years on from the Bluetooth Special Interest Group’s (SIG) announcement of a new specification that defined a high quality, low-power audio codec that promised to redefine audio streaming and wireless sound, Bluetooth LE Audio is finally about to hit the commercial mainstream.

Bluetooth LE Audio and Auracast going mainstream will redefine wireless audio

Wearable electronic devices designed to be worn while in use are becoming more popular and powerful as they can monitor various aspects of human health, activity, and environment. However, these devices also face challenges such as limited battery life, data privacy, and network bandwidth. To overcome these challenges, edge computing and AI/ML are emerging as key technologies that can enable wearable devices to process data locally, reduce latency, and enhance user experience.&nbsp;As wearable technologies evolve to meet market needs, new devices are upgrading features such as basic BLE connectivity by adding the ability to run AI algorithms on neural processors on-device rather than in the cloud. This reduces the amount of data that needs to be transmitted over the network, saving energy and bandwidth. With the AI/ML models running in silicon, wearable devices can, therefore, learn from data and perform tasks such as recognition, classification, prediction, and optimization without incurring additional latency, data costs, and power consumption. However, these improvements require greater processing power and capabilities from embedded microcontrollers (MCUs) and application processors. At the same time, consumers expect longer battery life from their wearables. Thus, new chips must balance connectivity and higher processing power with low power consumption while maintaining a small enough package size.&nbsp;This case study explores the challenges for the next generations of wearable MCUs with a specific look at <a href="https://alifsemi.com/" target="_blank" rel="noopener noreferrer">Alif Semiconductor's®</a> Balletto™ family of BLE-enabled MCUs for wearable applications.<h2 dir="ltr">The current landscape</h2>The wearables market, which includes common accessories such as smart bands, smart rings, smartwatches, and medical devices, such as glucose monitoring devices is projected to grow to USD 118.16 billion by 2028 at a 13.8% CAGR. Demand for multimedia devices, smartphones, fitness trackers, and health wearables drives growth. Increasing health awareness fuels interest in fitness tracking devices for activities like cycling and running, contributing to market expansion.[2,3]Wearables have evolved significantly in recent years, presenting enhanced capabilities in various domains, such as AI processing and wirelessly transmitting data. New market demands have driven the expansion of wearable features. For example, the COVID-19 pandemic made blood oxygen sensing a must-have feature for many smartwatches. As a result, Apple and Samsung included blood oxygen monitoring in their smartwatches in 2020.Wearables incorporate edge AI-based solutions to process huge amounts of data in real-time. AI-enabled microcontrollers are a must to carry out these large AI/ML workloads efficiently and quickly. The integration of artificial intelligence enables new features, such as:<ul><li dir="ltr">Tracking and analyzing changes in users’ health data.</li><li dir="ltr">Sending users alerts for noise levels or air quality.</li><li dir="ltr">Personalize your device based on your tracked activity.&nbsp;</li></ul>Equally important as collecting and processing user data is the ability to wirelessly share data between devices. As such, Bluetooth connectivity has risen as a top requirement for wearables including functionalities, such as:&nbsp;<ul><li dir="ltr">Sending an alert to emergency services if a fall is detected.</li><li dir="ltr">Sharing important health updates with an approved health care professional.</li><li dir="ltr">Sharing workout metrics with a friend to stay motivated.</li></ul><h2 dir="ltr">Bluetooth LE changes the status quo in wearables</h2>Among the many low-power wireless technologies on the market, Bluetooth Low Energy (BLE) technology is uniquely suited for wearable devices that require long battery life measured in days or even weeks before needing to be recharged. BLE allows wearables to easily connect and communicate with other devices, such as smartphones, tablets, exercise equipment, or even other wearables.&nbsp;This enhances the device's functionality by enabling it to share exercise data, receive timely notifications, and more. Increasingly, wearable devices are adding audio support for which BLE is uniquely positioned. With the addition of support for the Low Complexity Communication Codec (LC3), BLE is now capable of use cases such as broadcast audio and shared or group listening experiences with LE Audio’s Auracast feature. For example, a wearable device can use the on-device neural processor such as Arm’s Ethos-U55 to run a convolutional neural network (CNN) model for gesture recognition or activity classification based on the motion data captured by inertial measurement units (IMUs). The device can then use BLE to communicate with other devices or a smartphone app to provide feedback or instructions to the user.&nbsp;In the Smart Home, wearables can be integrated into a smart home system, with AI algorithms learning the user's habits and preferences to automate various home appliances. BLE 5.4's enhanced performance and range can facilitate efficient communication with many IoT devices in the home. For example, a wearable could learn that a user likes to listen to calming music when they get home from work and automatically instruct the smart speaker to play the user's favorite playlist when they walk through the door.&nbsp;Additionally, features allow wearables to be located precisely, while location-based services (LBS) such as personalized fitness coaching (created by learning from a user’s previous workout data) can be enabled. It can suggest workout routines tailored to the user's fitness goals and current health status. The wearable device can recognize the user’s activity and posture using an ML model that runs on the Ethos-U55 core and sends the data to a cloud service via Enhanced Attribute Protocol (EAP). This could enable personalized, reliable, and secure fitness tracking for the user.&nbsp;<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEzMTY0MTY0MDQ1LVdob29wLUJvZHlUcmFpbmluZy1Ub3AuanBnIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib">Next-gen wearables will enable highly-personal fitness tracking. Credit: WHOOP.&nbsp;AI/ML algorithms can be trained to detect patterns in biometric data gathered by wearables, such as heart rate, blood pressure, and oxygen saturation levels. BLE's enhanced broadcast communication mechanism (EAD, PAwR) can allow these devices to send real-time health risk alerts to other devices, such as a smartphone, even in congested or high-interference environments. For example, a wearable could alert a user or a healthcare provider if it detects signs of an impending health crisis like a heart attack or stroke.&nbsp;When you combine AI-enabled MCUs with BLE, wearables become more personalized, efficient, secure, and useful in our everyday lives. Alif Semiconductor <a href="https://alifsemi.com/press-release/first-ble-matter-wireless-microcontroller-with-neural-co-processor-for-ai-ml/" target="_blank">has just announced</a> their Balletto family of BLE and Matter microcontrollers&nbsp;with neural processing for AI/ML workloads, which seeks to exceed the standard for low-power BLE operations.<h2 dir="ltr">Hardware accelerated machine learning</h2>To meet the market-need for state-of-the-art wearables, Alif Semiconductor offers AI/ML-enabled microcontrollers with dedicated NPU accelerators that allow heavy AI/ML workloads to run without compromising battery life. <a href="https://alifsemi.com/products/balletto/" target="_blank" id="isPasted">The Alif Balletto family</a> of microcontrollers introduces the world's most power-efficient microcontroller with on-device secure AI/ML processing, top-notch security, and ample peripherals for applications requiring integrated Bluetooth Low Energy and 802.15.4-based connectivity.&nbsp;The Balletto family boasts the powerful Arm® Cortex®-M55 core, equipped with double-precision FPU and Helium Vector Extensions, operating at a remarkable speed of up to 160MHz. Arm Ethos-U55 is a dedicated NPU accelerator that offloads AI/ML operations from the Cortex-M55 processor, allowing the M55 cores to operate in very low-power modes. This is especially important for wearables like hearing aids, which need to have a long battery life. Equally as important for wearables is having a small form-factor design, which Balletto can provide in a sub 16mm ² package. &nbsp;&nbsp;Balletto’s Ethos™-U55 Neural Processing Unit (NPU) can improve the performance and efficiency of speech recognition machine learning models by up to two orders of magnitude, excluding the 5-10x improvement already provided by the Cortex-M55 core over previous generation Cortex-M CPUs. This is ideal for wearables that rely on voice commands, improving processing speed and lowering latency.&nbsp;<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEyODQyNDU1ODU5LWFsaWYgbWFpbiAyLnBuZyIsImVkaXRzIjp7InJlc2l6ZSI6eyJ3aWR0aCI6OTUwLCJmaXQiOiJjb3ZlciJ9fX0=" style="width: 100%px;" class="fr-fic fr-dib">Balletto and Ensemble families. Image credit: Alif Semiconductor.<h3 dir="ltr" id="isPasted">Battery-friendly microcontrollers powered by Alif’s aiPM™ technology&nbsp;</h3>The Balletto family also tackles a common problem seen by previously existing AI/ML-powered microcontrollers: short battery life. Connected wearables or mission-critical devices like hearing aids depend on long battery life for users. Their ability to function is hindered when there is a need for heavy local processing and AI/ML. Balletto MCUs are the most power-efficient in their class, thanks to Alif's innovative aiPM technology. This technology manages all aspects of the device, including individual processing cores for real-time control, neural processing, DSP and audio, deep security, and radio protocols capable of BLE 5.4 with LE Audio, Thread, and Matter. Balletto devices also include a wide range of interfaces and large memories, all monolithically integrated inside extremely small packages. This makes them ideal for demanding battery-powered applications such as wearables and hearables.Alif Semiconductor’s aiPM technology manages the power usage of the device through 8 power domains. It activates only the necessary chip sections and deactivates them when not in use, resulting in a highly efficient always-on region when there is a high requirement for local processing and AI/ML. The integrated dual-PA and on-chip antenna gives customers control of the reliability-range equation by providing tuning options of 4 dBm or up to 10 dBm Bluetooth transmit power. &nbsp;Balletto’s Bluetooth radio has a receive current of 1.5mA and a transmit current of 2.0mA, making it power conscious.Additionally, off-die peripherals produce higher energy consumption for wearables, while Balletto’s on-die solution fosters maximum efficiency. Utilization of the internal bus fabric effectively lowers access time, dynamic power, and standby power, ultimately providing more granular and precise power control at a lower cost.&nbsp;<h3 dir="ltr">Balletto family multi-layered security</h3>In addition to handling processing requirements, microcontrollers for wearables must ensure data security.

Leading Wearables into a New Era with Cutting-Edge Connected Bluetooth LE based MCUs

Bluetooth&nbsp;LE, Wi-Fi&nbsp;6,&nbsp;and cellular IoT bring connectivity to low power IoT devices. The Nordic SoCs, companion ICs, and SiPs running these protocols are among the most power efficient wireless solutions on the market, extending devices’ battery life.&nbsp;But there’s more to managing power than just efficient chips; power from a battery or a mains source must be regulated and distributed, and if the device is powered by a rechargeable battery, it will occasionally need to be charged. That means no matter how efficient the processor, radio, and memory are in the wireless chip, a less-than-optimized power management system will compromise battery life.&nbsp;&nbsp;<h2>Building a compact power management system&nbsp;Into&nbsp;one small package&nbsp;</h2>Building an efficient power management system is one problem, designing it to be compact makes things even more challenging. Many IoT products are space constrained, yet conventional power management solutions typically comprise multiple chips—for example, voltage regulator, battery charger, fuel gauge, external watchdog, and hard reset—which take up precious space.&nbsp;Nordic has addressed both the efficiency and space challenges of power management with its nPM Family of&nbsp;<a href="https://www.nordicsemi.com/Products/Supplementary/Power-Management" target="_blank">Power Management ICs</a>&nbsp;(PMICs). The family comprises the nPM6001 (which features six independently controlled power rails), nPM1100 (a dual-mode configurable buck regulator and integrated battery charger) and the latest introduction, the nPM1300. This PMIC is optimized for maximum efficiency and compact size and simplifies system design by integrating the essential functions required for reliable operation into one small package.&nbsp;<h2>Intelligent power management from the nPM1300&nbsp;</h2>Within its 5 by 5 mm (QFN32) or 3.1 by 2.4 mm (WLCSP) compact form factor, the nPM1300 incorporates two buck converters, two load switches, a battery charger, USB-C compatible input, ship mode, and fuel gauge. This simplifies power management from as many as eight chips plus associated passives to one chip plus a few passives.&nbsp;In addition to the high level of integration, the PMIC provides key system management features that typically must be individually added to conventional power management circuits. These features include key items such as failed boot recovery, hard reset, a power saving ‘hibernate’ mode, watchdog timer, and a power loss warning.&nbsp;<h2>Precise fuel gauging without the power drain&nbsp;</h2>It’s very useful for a consumer to have an accurate idea of the remaining battery life of their IoT device. Engineers typically achieve this by measuring the battery voltage—which is a proxy for remaining energy—or, for a more precise result, a coulomb counter, a device that continuously measures the current flowing into or out of a battery to determine the total cell charge.&nbsp;&nbsp;The battery voltage measurement is simple to implement and uses little power, but is not very accurate, particularly if the battery is subject to temperature variances. The coulomb counter is more precise but requires additional components and drains more power. In comparison, the nPM1300 features a highly accurate fuel gauge that combines the simplicity and modest power consumption of a battery voltage measurement with the precision of a coulomb counter.&nbsp;&nbsp;Nordic conducted experiments that compared a coulomb counter, battery voltage measurement, and the nPM1300’s fuel gauge. Compared to the coulomb counter, the battery voltage calculation peaked at nearly 20 percent error. In comparison, the nPM1300’s fuel gauge showed a maximum of two percent error at worst compared with the coulomb counter but was mostly within one percent.&nbsp;&nbsp;<h2>Fuel gauge powered by software&nbsp;</h2>The key to Nordic’s fuel gauge’s accuracy over a wide temperature range is the software algorithm powered by the host processor. The processor uses information such as the current flowing out of the battery, the battery terminal voltage, the system voltage, and a battery temperature thermistor reading.&nbsp;&nbsp;For the algorithm to produce accurate results it must first be ‘taught’ the battery characteristics (which only has to happen once if the end product continues to use the same type of battery). The teaching is done using the Nordic&nbsp;<a href="https://www.nordicsemi.com/Products/Development-hardware/nPM1300-EK" target="_blank">Evaluation Kit</a>&nbsp;(EK) equipped with a fuel gauge board to provide the right resistive load and the Nordic nPM PowerUP App.&nbsp;After calibration and with the current, voltage, and temperature inputs, the host processor uses the Nordic-developed algorithm to accurately determine the battery’s state of charge for the life of the device. Power consumption for a one-second measurement frequency adds about four microamps to the typical host processor overhead.&nbsp;<h2>Managing power from&nbsp;battery to antenna&nbsp;</h2>Maximizing battery life demands taking responsibility for how each part of the wireless product’s system affects the overall power consumption. The developer needs to optimize each element—from the battery all the way to Cloud connectivity, including radio operation, processing, and power management—to get the most from the power source. &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;Basing a design on a Nordic SoC or SiP—among the lowest power wireless chips on the market—together with a Nordic nPM6001, nPM1100, or nPM1300 is an excellent foundation for keeping the energy consumption of wireless products as low as possible.&nbsp;

Bluetooth LE, Wi-Fi 6, and cellular IoT bring connectivity to low power IoT devices. The Nordic SoCs, companion ICs, and SiPs running these protocols are among the most power efficient wireless solutions on the market, extending devices’ battery life. 

Inside the next generation of efficient and compact power management

Every&nbsp;day, the average&nbsp;person inhales a staggering 11,000 liters of air,&nbsp;amounting to more than 300 million liters over a lifetime (as reported by&nbsp;TheWorldCounts).This remarkable intake underscores the importance of ensuring the air we breathe is fresh and clean, especially since, according to the World Health Organization, there are over 6.7 million premature deaths annually due to air pollution, with more than 3.2 million of these stemming from indoor environments. &nbsp;&nbsp;Despite the common focus on outdoor air pollution, significant health risks also originate from the air indoors. With people spending increasing amounts of time inside homes, offices, shops, gyms and restaurants&nbsp;it has become even more important to monitor the air quality of these environments.&nbsp;<h2>The next phase of air quality monitoring&nbsp;&nbsp;</h2>Carbon monoxide alarms have been around for&nbsp;almost a&nbsp;century,&nbsp;while&nbsp;traditional&nbsp;smoke detectors&nbsp;have been around for over seventy years. But wireless technology represents a new level of air quality measurement. For example,&nbsp;whereas&nbsp;previously conventional&nbsp;alarms&nbsp;only&nbsp;issued warnings when dangerous levels&nbsp;of carbon monoxide or smoke&nbsp;were detected, the advent of wireless technology&nbsp;allows&nbsp;for&nbsp;a more nuanced and&nbsp;timely&nbsp;response&nbsp;to potential hazards, especially in cases of long-term, low-level exposure.&nbsp;The effects of such exposure shouldn’t be taken lightly. According to an article by Julie Connolly, Senior Lecturer in Health and Social Care at Liverpool John Moores University, the symptoms of low-level carbon monoxide exposure can be difficult to spot. And yet,&nbsp;they have been linked to such serious symptoms as musculoskeletal injury, fatigue, and memory loss.&nbsp;&nbsp;Beyond concerns like natural gas leaks, or carbon monoxide, carbon dioxide, and smoke build-up, humans present risks to fellow humans through viruses (such as COVID-19 or influenza). And certain strains of bacteria and mold spores also pose a threat to air quality.&nbsp;One of the most serious threats, however, is from Volatile Organic Compounds (VOCs). These can lead to serious health issues, including eye, nose, and throat irritation, headaches, loss of coordination, nausea, and potential damage to the liver, kidneys, and central nervous system (according to the U.S. Environmental Protection Agency). Worse still, some VOCs have even been linked to cancer.&nbsp;<h2>Creating smart&nbsp;IoT&nbsp;systems&nbsp;for air&nbsp;quality monitoring&nbsp;</h2>Now the IoT can be used to alert building occupants of these hazards, in near real-time. This allows individuals and companies to proactively implement changes to help ensure healthy indoor environments and prevent health problems.&nbsp;Moreover, smart air purification and filtration systems can be integrated into smart home systems or an intelligent HVAC (Heating, Ventilation, and Air Conditioning) unit in a commercial building. A feedback loop can then be formed between the sensor network and the air purification system. When sensors detect the air quality dropping the system can automatically boost purification.&nbsp;&nbsp;<h2>The advantages of Bluetooth LE and Wi-Fi&nbsp;&nbsp;</h2>There are many advantages of employing wireless technology in these applications. Technology such as&nbsp;<a href="https://www.nordicsemi.com/Products/Wireless/Bluetooth-Low-Energy" target="_blank">Bluetooth LE</a>&nbsp;suits compact, low-power sensors working over hundreds of meters while low-power&nbsp;<a href="https://www.nordicsemi.com/Products/Wireless/WiFi" target="_blank">Wi-Fi</a>&nbsp;technology such as Nordic’s nRF70 Series suits sensors that need a bit more bandwidth. Bluetooth LE and Wi-Fi can also work together in gateways, with the Bluetooth LE signal coming from a network of sensors, while the Wi-Fi part of the gateway sends the data to the Cloud. &nbsp;&nbsp;Because these solutions need no wiring, they are simple to integrate into new builds or retrofit existing buildings. Compact, battery-powered sensors (such as carbon monoxide detectors) can easily be strategically installed near fossil-fuel heaters, in rooms with poor ventilation, and in other areas of concern.&nbsp;Once these sensors have been set up, they continuously gather data. Edge computing enables the device to only forward information to a gateway or central device when significant to trigger further decisions such as increasing ventilation. Alternatively, the data can be sent directly to the user’s smartphone via Bluetooth LE for instant notifications. Multiple types of sensors and wireless tech enable users to build the optimum solution for the application. &nbsp;&nbsp;<h2>Nordic Bluetooth LE SoCs power multisensory air quality monitor &nbsp;&nbsp;</h2>For example, the&nbsp;<a href="https://www.nordicsemi.com/Nordic-news/2023/10/The-AirSuite-Glance-environment-monitor-employs-the-nRF9160-SiP-and-nRF52840-SoC" target="_blank">AirSuite Glance</a>, created by New Zealand company AirSuite, employs a range of sensors to monitor carbon dioxide (CO2), temperature, humidity, sound, lighting, air pressure, and volatile organic compounds (VOCs). It uses the Bluetooth LE connectivity provided by Nordic Semiconductor’s&nbsp;<a href="https://www.nordicsemi.com/products/nrf52840" target="_blank">nRF52840</a>&nbsp;SoC to transmit the data directly to the user’s smartphone every minute, and the LTE-M or NB-IoT connectivity of the&nbsp;<a href="https://www.nordicsemi.com/products/nrf9160" target="_blank">nRF9160</a>&nbsp;SiP to send it to the Cloud at least every fifteen minutes.&nbsp;Through the dedicated app and web platform, users can oversee and receive notifications when environmental metrics surpass or fall below predetermined thresholds. Additionally, the AirSuite Monitor Web Portal offers access to historical data, allowing users to analyze trends and compare values across various rooms or sites.&nbsp;<h2>Intelligent adjustment with machine learning &nbsp;&nbsp;</h2>There are many innovations currently shaping the landscape of indoor air quality monitoring. Notably, the development of more advanced wireless sensors—low power devices that can run for years between battery replacements—and the advancement of Machine Learning (ML)-driven analytics.&nbsp;&nbsp;ML, with its pattern recognition capabilities, can identify trends, and intelligently adjust settings to optimize occupant health and comfort. The system can autonomously adjust settings in response to&nbsp;certain stimuli—such as switching on an air purifier in anticipation of the increased building occupancy expected at certain times of the day. This reduces power consumption by avoiding unnecessary equipment use and helps create indoor environments that can be continually optimized for the occupants’ wellbeing.

Every day, the average person inhales a staggering 11,000 liters of air, amounting to more than 300 million liters over a lifetime (as reported by TheWorldCounts).

Ensuring the Safety of Fur Babies: The Role of GNSS in Advanced Pet Trackers

Cities around the world are experiencing a period of rapid expansion. According to the United Nations (UN), 57 percent of people already live in urban areas - and this is set to increase to almost 70 percent by 2050.&nbsp;&nbsp;In the time it takes you to read this blog, approximately 40,000 new IoT devices will connect to the Internet. At that rate, by 2030, we will have 30 billion connected IoT devices worldwide, or so Statista predicts. The numbers are huge, but to paraphrase software company Intuit co-founder Scott Cook, we’re still in the first minute of the first day of the IoT revolution. You ain’t seen nothing yet.&nbsp; While the average man or woman on the street may still not yet heard of the “Internet of Things”—a term first coined 24 years ago by British computer scientist Kevin Ashton—the reality is it’s changing the world every day, in almost every way. From sustainability, healthcare, and education to our homes, places of work and social lives, the IoT is having an impact on us all in untold ways. Here are some of the wireless IoT applications that could, should, and are, changing our world.&nbsp;<h2>How cellular IoT and AI help reduce food loss and waste in farming</h2>Human beings have certain basic needs. We must have food, water, air, and shelter to survive. The lucky ones amongst us take these needs for granted, but not everyone is so fortunate. At least 345 million people face high levels of food insecurity, according to the World Food Programme, and by 2050, we will have a billion more mouths to feed than we do now.&nbsp; Food loss and waste occurs throughout the supply chain. According to a Coresight study, farms contribute 21 percent of food waste, processing 14 percent, food service and retail 28 percent, and consumers waste as much as 37 percent of the food they buy.&nbsp; To address farming losses <a href="https://www.nordicsemi.com/Products/Low-power-cellular-IoT" rel="noopener" target="_blank">cellular IoT wireless connectivity</a> supported by AI and analytics is providing farmers a detailed picture of their crops and livestock using a combination of connectivity solutions including sensors, autonomous machines, and drones. Drones can be used for crop health monitoring and disease detection, while autonomous robots can scan harvests from the ground level for signs of pests, weeds, or disease. Meanwhile machine learning (ML) algorithms and GNSS positioning are being used to develop self-driving harvesting machinery, significantly boosting yields and reducing harvesting losses.&nbsp;<a href="https://blog.nordicsemi.com/getconnected/how-the-iot-can-help-create-a-more-sustainable-future" rel="noopener" target="_blank"></a><h2>Reducing food waste in retail with Bluetooth LE and cellular IoT</h2>At the retail level, a recent study from U.C. San Diego’s Rady School of Management found dynamic pricing could reduce food waste from grocery retailers by 21 percent. Bluetooth LE-powered shelf labels and cellular IoT Cloud-connected gateways have enabled dynamic pricing by applying an algorithm that determines when the price of perishables should be lowered based on their expiration date, and automatically applying the revised price using wireless connectivity direct to the shelf.<h2>Bluetooth LE SoCs and cellular IoT SiPs saving future healthcare wearables</h2>Wearable tech has come a long way in 10 years. Today’s wearables powered by&nbsp;<a href="https://www.nordicsemi.com/Products/Bluetooth-Low-Energy" target="_blank" rel="noreferrer noopener">sophisticated wireless SoCs</a>&nbsp;are multifunctional devices that can not only provide fitness motivation but also have the ability to play a valuable clinical role. Ironically, to some extent, we have the pandemic to thank for the development of high-end healthcare wearables, but now these devices are playing a vital role in the prevention and management of a host of other diseases from diabetes, high blood pressure and sleep apnea through to neurocognitive disorders such as Parkinson’s Disease and Alzheimer’s. Soon enough, high-end SoCs and SiPs running ML routines will enable&nbsp;<a href="https://www.nordicsemi.com/Applications/Wearables" target="_blank" rel="noreferrer noopener">wearables</a>&nbsp;to rapidly establish health data anomalies, and seamlessly relay the data via the Cloud to our doctors resulting in rapid clinical decisions.&nbsp;<h2>Supporting&nbsp;the next generation of&nbsp;tech&nbsp;education&nbsp;</h2>In the education sector, wireless tech is both democratizing learning and simultaneously addressing the digital skills gap. We need more coders, engineers and tech innovators, and devices such as the&nbsp;<a href="https://microbit.org/" target="_blank" rel="noreferrer noopener">BBC micro:bit</a>&nbsp;are supporting the next generation of digital innovators. The micro:bit program was launched in 2015, and with a million wireless chips donated by&nbsp;<a href="https://www.nordicsemi.com/" target="_blank" rel="noreferrer noopener">Nordic Semiconductor</a>, the program was up and running. Since then, the tiny yet powerful programmable pocket computers have found their way into the hands of 39 million children in over 60 countries, across every continent. The 11 and 12 year olds that received the first micro:bits are now at university age, and soon we will see these pioneers enter our workforce equipped with the digital coding skills their predecessors lacked.&nbsp;&nbsp;<h2>Wireless connectivity protecting the world</h2>The IoT might be able to transform our food supply, health, and education, but all of that is pointless without a sustainable planet to live on. And there, arguably, wireless connectivity is making a more telling contribution than in any other domain. Wireless connectivity is providing answers to&nbsp;<a href="https://www.nordicsemi.com/Nordic-news/2021/03/Holding-the-Line" target="_blank">illegal deforestation</a>, waste management, pollution control, electric vehicles, and ecosystem protection just for starters.&nbsp;&nbsp;Whether it’s customized cellular IoT devices installed on construction vehicles to prevent illegal logging, smart bins in cities employing optical sensors to better allocate rubbish collection and overflow, connected air quality and climate monitoring solutions to provide authorities with data to help manage traffic and emissions, or Bluetooth LE,&nbsp;<a href="https://www.nordicsemi.com/Products/WiFi" target="_blank">Wi-Fi</a>,&nbsp;and cellular IoT connectivity helping electric vehicle (EV) charging companies manage the complex EV ecosystem to boost clean transport, wireless connectivity is now everywhere, and promising a smarter, greener way to protect our precious planet.&nbsp;&nbsp;

Cities around the world are experiencing a period of rapid expansion. According to the United Nations (UN), 57 percent of people already live in urban areas - and this is set to increase to almost 70 percent by 2050.  

The cellular IoT and Bluetooth LE wireless IoT applications changing our world

Wireless technology saves lives every day, sometimes in extraordinary ways. After spotting flames rising from a residence in Scotts Valley, California, a passing jogger rang the doorbell in an effort to notify the homeowners. The owner wasn’t home, but the wireless doorbell was connected to a smart home hub that alerted her to the jogger’s attempt to make contact. In an instant she provided him with the security code, enabling him to run into the house to rescue her pets from the fire.Texan Joey Lowe was equally fortunate when he passed out on his porch on a very hot summer’s day. His wife and son were out of town but received a motion alert from their smart home doorbell app when he collapsed, and were able to contact a neighbor who called 911 to transport Joey to hospital to treat the cardiac episode.Not every instance of technology keeping us safe is so dramatic, but as the ‘Internet of Everything’ delivers ubiquitous connectivity at home, at work and at play, wireless devices are keeping a watchful eye on us as never before.<h2>Safety begins with a smart home</h2>The smart home is still viewed with caution by some observers as interoperability, cost, and ease-of-operation concerns in particular have cooled consumer interest. We are all aware of the tech—from smart lights and energy management, to devices designed purely for convenience—but how many of us actually use it? According to analysts, around 16 percent of homes currently employ some form of smart technology, but the numbers are trending upwards rapidly as the industry addresses standardization concerns.Unifying connectivity standard <a href="https://www.nordicsemi.com/Products/Matter" target="_blank">Matter</a> will deliver consumers greater simplicity, ensuring, for example, any Amazon Echo device can control any third party smart home security product, or any other Matter smart home device. This interoperability should act as an accelerant for smart home tech where security above convenience is also driving renewed interest from consumers. As fun as it might be to remotely and wirelessly control our lights, air conditioning or blinds, keeping our castle safe from uninvited intruders is a more pressing concern.As such the market has been flooded with simple, user-friendly, easy-to-set-up wireless security systems, fully controlled and programmed via a smartphone app. These systems enable remote, wireless locking and unlocking, and the ability to issue temporary access to tradespeople or babysitters without handing over precious keys or lock combinations. An owner can also be notified if a lock is being tampered with, even if they are on the other side of the world.And not every threat to our safety at home comes in human form. Wireless smart smoke and carbon monoxide detectors can alert smart home owners via a smartphone app in the event of an issue – whether they are at home or not. They can detect steam from smoke, can be disabled from the app in the event of a false alarm, and tell you when the batteries are running low, without the device ‘chirping’ at you in the middle of the night.<h2>Transforming workplace safety with wireless technology</h2>The pandemic may have spawned the work-from-home movement, but not all of us are fortunate enough to be able to earn a living from our living room. For those people—first responders, construction laborers, and farmers for example—who need to venture past their front door for their employment, wireless tech is also transforming workplace safety.People working alone are at particular risk of workplace accidents, where the ability to trigger warnings may not be an option if someone becomes incapacitated. Wearable, wirelessly-connected devices employing a raft of sensors that can automatically trigger an alert to an employer or first responders are increasingly commonplace, particularly in potentially hazardous work environments like mines, farms and heavy industry.For example, using explosives in mining operations to break mineral-bearing rocks can result in toxic fumes lingering for hours. In-situ or wearable environmental sensors can ensure downtime is minimized and that workers don't re-enter the blast site until it is safe. Similarly, exhaust fumes emitted from underground excavating equipment and drilling machines can be kept within limits by monitoring with gas detectors and particle sensors.On farms, checking there is enough grain to feed livestock is traditionally a manual exercise. Aside from the risks of falling, inhaling dust emissions or the aspiration of silage gas can be extremely harmful, and like mines, explosion and fire are also real threats. Wireless connectivity allows tanks in remote agricultural locations to report level sensor data so the farmer can monitor feed, fuel, water, or fertilizer levels through a Cloud platform, using their smartphone, tablet, or computer.<h2>The power of cellular IoT wireless technology</h2>The catalyst for many of these remote monitoring solutions is the capabilities of mature <a href="https://www.nordicsemi.com/Products/Low-power-cellular-IoT" rel="noopener" target="_blank">cellular IoT</a> technology and the increasing ease with which it can be integrated into new solutions and application areas.Mines and farms are often isolated, but cellular IoT network infrastructure is ever expanding and is increasingly available even in remote locations. The technology can either power a gateway to pass data from a group of Bluetooth LE IoT devices to the Cloud or power sensors with end-to-end IP connectivity. Base stations can support tens of thousands of cellular IoT connections, and the communications are fully bidirectional, robust, reliable, and secure. Moreover, NB-IoT can penetrate further below ground than other wireless IoT technologies.<h2>Playing it safe with wireless technology</h2>Outside of our homes and our places of work, wireless technology is also keeping us safe in other ways. In the last five years wearable devices that double as safety devices have proliferated. Today’s ultra miniaturized <a href="https://www.nordicsemi.com/Products/Bluetooth-Low-Energy" target="_blank">SoCs</a> and SiPs enable designers to embed wireless connectivity in imaginative form factors such as bracelets or necklaces that double as panic buttons.For these personal safety device applications, Nordic’s <a href="https://www.nordicsemi.com/Products/nRF9160" rel="noopener" target="_blank">nRF9160</a> low power SiP with integrated LTE-M/NB-IoT modem and GNSS can provide cellular IoT wireless connectivity between the device and the Cloud, eliminating the need for a smartphone or gateway. The nRF9160 SiP combines LTE-M cellular network location data with GNSS trilateration for precise position monitoring, while the nRF9160’s assisted and predictive GNSS also saves power by speeding up time-to-first-fix (TTFF) on the satellites.And while wireless wearables have long been synonymous with keeping fit and urging us to increase our daily activity, they are now by design trying to keep us safe in the process. For example, cycling while a hugely popular pastime around the world, is also frequently hazardous. In 2020, The U.S. Consumer Product Safety Commission reported nearly 426,000 emergency department-treated injuries associated with bicycles.Using Bluetooth LE-powered sensors and GPS, cycling helmets can now be transformed into a live GPS tracker, crash detector and safety beacon. Cycling equipment leader, <a href="https://www.nordicsemi.com/Nordic-news/2019/02/ANGi-sensor-based-device-transforms-cycling-helmet-using-nRF52832" rel="noopener" target="_blank">Specialized launched one such device</a> that uses a built-in accelerometer and gyroscope to detect any potentially dangerous incident by the measurement of linear and rotational forces to the cyclist’s head that typically occur during a bicycle crash. When it detects the possibility of a serious accident, it launches a countdown alert on the partner smartphone app. If the rider is uninjured they can then manually cancel the countdown. However, if the rider is injured and unable to cancel the countdown, the app sends a text alert notifying the user’s emergency contacts of a possible accident. In addition, the rider’s location—established by the device’s most recently uploaded GPS coordinates—is immediately sent to all contacts.It is one example among many of wireless technology making everyday life simpler, safer, and healthier for billions of us.<hr>This article was first published on Nordic's&nbsp;<a href="https://blog.nordicsemi.com/getconnected" target="_blank" rel="nofollow" id="isPasted"></a><a href="https://blog.nordicsemi.com/getconnected?utm_campaign=2021%20wevolver" target="_blank" rel="nofollow">Get Connected Blog</a>. &nbsp;

As things stand now, a global technology talent shortage threatens to stifle progress across all tech sectors.Fortunately, it’s not all doom and gloom in the classroom. There’s a long way to go, but industry leaders are working hard to close the digital skills gap.<h2>Filling the gaps</h2>In 2021 there were more than two million U.K. job vacancies in tech, more than any other labor area. Yet a large section of the British workforce is apparently nowhere near skilled enough to apply for many of these tech-based positions. According to FutureDotNow—a coalition of industry leaders focused on closing the digital skills gap for working age adults—some 11.8 million U.K. workers lack even basic digital skills.In its 2022 Digital Strategy, the U.K. government asserted that while over 80 percent of all jobs advertised in the U.K. now require digital skills, employers say the lack of available talent is the biggest factor holding back growth. Estimates suggest the digital skills gap costs the U.K. economy as much as £63 billion ($79 billion) a year in potential GDP.This gap not only plays an important role in the U.K.’s economic prospects but also in an individual’s life chances. The Department for Digital, Culture, Media and Sport report in 2019 found: “The move up the career ladder from low- to high-skill jobs comes with increased demand for specific digital skills. Acquiring specific digital skills makes career progression and a pay increase more likely.”<h2>Responding to the challenge with micro:bits</h2>In March 2015, in response to the significant skills shortage across the U.K. at the time, the British Broadcasting Corporation (BBC) launched Make It Digital, a nationwide initiative focused on creating the next generation of digital pioneers. One year later, the project spawned the delivery of one million Nordic-powered BBC micro:bits—tiny yet powerful programmable pocket computers—to Year 7 school students throughout the country’s schools. It was hoped the device could transform young people from passive consumers of technology into digital innovators via the power of ‘coding’.Within six months the not-for-profit <a href="https://microbit.org/" rel="noopener" target="_blank">Micro:bit Educational Foundation</a> was established to promote the micro:bit project internationally. To this day the foundation works in collaboration with educators to create curriculum materials, training and resources that empower a young person’s creativity and boost their opportunities in an equal and purposeful way.<h2>Overcoming inequality</h2>The foundation has good reason to focus its efforts on overcoming inequality in education. Research indicates that factors such as socio-economic background can have a significant impact when it comes to children learning about coding. A 2022 report by Ofsted (the U.K. Office for Standards in Education, Children's Services and Skills) revealed that state schools with higher proportions of disadvantaged pupils were&nbsp;less likely to offer a GCSE (General Certificate of Secondary Education) in computer science.The gap between genders is also pronounced. Analysis of examination data from 2021 shows there are&nbsp;disproportionately few girls in computer science, making up just 21 percent of entries at GCSE and 15 percent at the GCE (General Certificate of Education) Advanced (A)-Level (a U.K. subject-based qualification for students aged 16 and above). Last year, computing A-Level continued to have the highest gender gulf of entrants, while the U.K. tech industry comprises only 26 percent women.<h2>Full STEAM ahead with micro:bits</h2>Seven-and-a-half years on from the launch of the, adoption is tracking impressively. Over 7 million micro:bit units have been sold worldwide. The device continues to be actively embedded in children's learning at schools and other education systems. Around 39 million young people in over 60 countries—including Denmark, Finland, Uruguay, Singapore, Canada and Bangladesh—have so far used the micro:bit to get hands-on with computer science and technology, learning important digital skills in the process.And STEAM [science, technology, engineering, the arts, and mathematics] education programs are making a meaningful difference. In Bangladesh, for example, where less than half of the country’s 47 million children will attend school beyond the age of 15, the British Council has provided free workshops to increase public access to digital skills training and to teach children to create technology, not just consume it. The first phase of the program reached 2,000 young people in 12 districts.Most participants (88 percent) were aged 12-16, with a fairly balanced gender split of 51.5 percent male and 48.5 percent female. The majority had never coded before, and 13 percent said the workshop was their first time using a computer. But 95 percent of participants said they would be interested in learning more coding in the future. And 70 percent more girls said they would choose computing as a subject at school after using the micro:bit.<h2>Powering the micro:bit journey</h2>Nordic Semiconductor has played a vital role from day one of the micro:bit journey. The company donated the first one million nRF51822 chips to kickstart the micro:bit, and later supported a smooth transition from the micro:bit V1 to the micro:bit V2 device integrating the Nordic <a href="https://www.nordicsemi.com/products/nrf52833" target="_blank">nRF52833</a> SoC as its core processor. The nRF52820 has also since been added to the board as the micro:bit’s interface chip.In addition to processing capabilities, the micro:bit’s Nordic-enabled wireless connectivity is used in two distinct ways. First, using the device firmware update (DFU) tools in the Nordic software development kit (SDK), the micro:bit has the capability to be updated from a phone or tablet over Bluetooth LE. This means schools or students without access to laptops can still easily use the micro:bit. And second, it provides a student-facing feature, which can be used with either a set of Bluetooth services or with the micro:bit radio feature.<h2>The Micro:bit Educational Foundation: Shaping the future</h2>The micro:bit’s achievements to this point are just the beginning. The Micro:bit Educational Foundation has now joined forces with BBC Education and Nominet (the U.K.’s official domain name registry) to launch “BBC micro:bit – the next gen”, a nationwide initiative to ready U.K. primary school children aged 8 to 11 for the digital world, once again empowering them with the skills to shape their future. The campaign will offer&nbsp;30 micro:bit devices&nbsp;to every primary school in the country – a giveaway of almost 700,000 micro:bits.Whether programming it for useful functions such as a sunlight sensor or a step counter, or using it for an exciting treasure hunt challenge, the Nordic nRF52833 SoC-powered micro:bit will continue to teach practical computer knowledge in an accessible and authentic way. As the micro:bit evolves, the foundation hopes the device will inspire all children to create their best digital future.<hr>This article was first published on Nordic's&nbsp;<a href="https://blog.nordicsemi.com/getconnected" target="_blank" rel="nofollow" id="isPasted"></a><a href="https://blog.nordicsemi.com/getconnected?utm_campaign=2021%20wevolver" target="_blank" rel="nofollow">Get Connected Blog</a>. &nbsp;

Without the coders, engineers, entrepreneurs, and innovators of tomorrow emerging from the classrooms—and soon—it will become increasingly difficult to advance society and tackle diverse global challenges. As things stand now, a global technology talent shortage threatens to stifle progress across all tech sectors.

Empowering next gen digital innovators with micro:bits

Smart lighting is a key component of smart commercial buildings and the connected home. Based on LEDs—which use at least 75 percent less energy, and last up to 25 times longer than traditional incandescent lighting, according to the U.S. Department of Energy (DoE)—combined with Bluetooth LE SoCs like Nordic’s nRF52, nRF53, and the forthcoming <a href="https://www.nordicsemi.com/Products/nRF54H20" rel="noopener" target="_blank">nRF54 Series</a>, smart lighting brings illumination into the modern age.Not only can intelligent lighting minimize energy usage, by, for example, dimming when ambient light conditions brighten or switching off when people are not present, but it can also form a platform for other sensors such as proximity monitors and air quality sensors.The Bluetooth Special Interest Group (SIG) was quick to promote Bluetooth LE as a good connectivity option for smart lighting by highlighting the economies of scale that only the most widely deployed wireless radio standard in the world can provide. A further advantage is that Bluetooth LE is interoperability with almost every smartphone on the market, enabling the mobile to become a convenient interface for commissioning and controlling smart lighting.But some tricky engineering challenges have threatened to stall smart lighting adoption. The good news is that first Bluetooth Mesh, and now the Bluetooth SIG’s recently announced Bluetooth NLC (Network Lighting Control) are providing solutions. &nbsp;<h2>Adding mesh networking to Bluetooth</h2>Bluetooth LE started life as a low power-consumption extension to Classic Bluetooth. In the early days it was designed for consumer type applications - for example wireless keyboards and mice or connecting peripherals such as fitness wearables to smartphones. Such applications require relatively simple peer-to-peer or star network topologies. In contrast, applications such as smart lighting—which features dense installations of wireless nodes—are best served by mesh networking.In a mesh network, every node can talk to every other node rather than being restricted to communicating with just a central master node. That brings advantages such as built-in redundancy: if a node fails, messages can simply be rerouted through alternative paths.To make Bluetooth LE more suitable for smart lighting, the Bluetooth SIG introduced Bluetooth Mesh. Making its debut in 2017, the tech offers features and options to create large-scale device networks. Without Bluetooth Mesh, individual lights are controlled from a central hub, restricting the position of each because it needs to remain in range of that hub. But with Bluetooth Mesh, a command rapidly propagates through the network with no position restriction on the lights - provided individual nodes are close enough together to communicate. It is also very easy to add or remove lights to or from the network.<h2>Bringing greater interoperability to smart lighting</h2>Bluetooth Mesh helped resolve some smart lighting engineering challenges but not all. The optional nature of Bluetooth Mesh’s features meant vendors had to choose a subset for their product segments. Challenges arose if vendors operating in the same product segments choose a set of options that didn’t work well with products from another vendor. For example, that made it frustrating for a consumer when features chosen for LED drivers from one maker were not compatible with features selected for light switches from another. Such problems undermined interoperability and consumer adoption.Ensuring complete interoperability requires standardization across radio-, communication-, and device-layer of a wireless lighting control solution. Interoperability was ensured at the radio layer by using the Bluetooth LE protocol, and the communication layer through Bluetooth Mesh. But until now there was no solution for the device layer.&nbsp;To address this challenge, the Bluetooth SIG has developed a class of specifications called Bluetooth Mesh Device Profiles. These profiles define which options and features of the Bluetooth Mesh specification are mandatory for a certain kind of end-product – thus ensuring interoperability between different manufacturers’ versions of that type of device.The first suite of mesh device profiles is collectively referred to as NLC profiles. According to the Bluetooth SIG, these profiles build on Bluetooth Mesh to form Bluetooth NLC, “the world’s first full-stack, multi-vendor interoperable wireless standard for wireless lighting control”.<h2>Taking advantage of Bluetooth NLC with nRF Connect SDK</h2>Nordic is the leading Bluetooth LE company in the world and is an enthusiastic supporter of Bluetooth Mesh and now Bluetooth NLC. That’s why we’ve immediately made it easier for developers to get started with the technology by including NLC profiles in the nRF Connect SDK.The <a href="https://www.nordicsemi.com/Products/Bluetooth-mesh/Development-software?lang=en#infotabs" rel="noopener" target="_blank">NLC profiles</a> in the software development kit can be used to implement interoperable network controlled lighting setups, including ambient light and occupancy sensors, light controller, energy monitoring, scene selectors, and dimmer controls. Each of the profiles specifies a set of models and a set of performance parameters. The nRF Connect SDK provides a demonstration of how to implement each of these profiles as part of the Bluetooth samples contained in the kit.<h2>A bright future for wireless smart lighting</h2>The shift from wired to wireless lighting control solutions is being driven by three main advantages: greater design flexibility, lower cost of deployment, and future extensibility.Wireless systems allow for optimal placement of switches, lights, and other equipment, including places where it would be impractical for wired systems. Without the need for control wires, wireless lighting controls offer lower deployment costs. Decreased labor and material expense, minimum disruption during installation, and reduced maintenance costs also bring substantial savings. Finally, once deployed, wireless systems are easier to extend and it is simple to add advanced controls.These advantages mean that wireless lighting is set to boom. The U.S. DoE, for example, forecasts that 28 percent of commercial lighting deployments will be wirelessly connected by 2035. With the interoperability Bluetooth NLC now brings to the device layer of wireless control systems, Bluetooth smart lighting will play a major role. The Bluetooth SIG says that Bluetooth NLC device shipments will grow at a CAGR of 115 percent between now and 2027. The future for smart lighting is very bright.<hr>This article was first published on Nordic's&nbsp;<a href="https://blog.nordicsemi.com/getconnected" target="_blank" rel="nofollow" id="isPasted"></a><a href="https://blog.nordicsemi.com/getconnected?utm_campaign=2021%20wevolver" target="_blank" rel="nofollow">Get Connected Blog</a>. &nbsp;

The world is working harder than ever before; U.S. workers, for example, toil for an annual average of 1,791 hours – that’s 34 hours every single week of the year. South of the border, Mexicans work even harder; a backbreaking 2,128 hours, or 41 hours across 52 weeks. (The numbers come from worldpopulationreview.com.) While attempts to introduce more working from home and even a four-day week are gathering steam, these figures suggest leisure time is still at a premium.That makes it important we spend it wisely, suggests the American Psychological Association. The association says there’s mounting evidence suggesting that taking breaks to relax and engage in hobbies outside of work is a vital component of maintaining happiness. And workers who take breaks also report higher job satisfaction and lower rates of burnout.Moreover, the Harvard Business Review found that dedicating time to hobbies can enhance an individual’s professional performance by fostering creative thinking and bolstering confidence. And consistently participating in leisure activities that incorporate exercise, like playing on a sports team or going to the gym, has the additional benefit of improving physical health. Now wireless tech is finding its place in helping us make the most of our non-work hours.<h2>Wireless fun at home</h2>Inside the home, <a href="https://www.nordicsemi.com/Applications/VR-and-AR?utm_campaign=2021%20wevolver" rel="noopener noreferrer" target="_blank">Virtual Reality (VR) and Augmented Reality (AR)</a> are moving in on traditional electronic gaming territory. Headsets and sound systems help players feel as if they are actually inside their favorite game. Wireless tech helps make the experience even more immersive by connecting headset and handset(s) for low-latency game control. <a href="https://www.nordicsemi.com/News/2023/08/Hisenses-XR-V3-employs-nRF52832-SoC?utm_campaign=2021%20wevolver" rel="noopener noreferrer" target="_blank">Hisense’s XR-V3</a>, which employs Nordic’s nRF52832 SoC to provide stable and reliable Bluetooth LE connectivity between the handheld controllers and headset, is a good example of this in action.And it’s not just the cutting edge of gaming that’s benefiting from wireless tech. Traditional <a href="https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwiOnLeIop-BAxVF_mEKHYLZB4EQFnoECBgQAQ&url=https%3A%2F%2Fwww.nordicsemi.com%2FNews%2F2022%2F08%2FXploreds-Teburu-employs-nRF52833-and-nRF52805-SoCs&usg=AOvVaw3QiFjIR2IqIFIr-zawIUhd&opi=89978449" rel="noopener" target="_blank">board games</a> use Bluetooth LE for connectivity through smartphone apps, which add interactive elements to the game. This can help create alternative rules, instructions or outcomes based on how users and pieces interact with a board, changing the gaming experience with each playthrough.<h2>On the go with wireless technology</h2>When we’re out walking or jogging, wireless headphones have enhanced the experience by making it easy to listen to content without getting tangled in cables.And things are about to get better with the introduction of <a href="https://www.nordicsemi.com/Products/Bluetooth-LE-Audio?utm_campaign=2021%20wevolver" rel="noopener noreferrer" target="_blank">Bluetooth LE Audio</a>. Described by the Bluetooth Special Interest Group as “the next generation of wireless audio”, LE Audio brings better audio quality, more robust connectivity and vastly improved battery life compared with Classic Audio. Such technical enhancements mean we can listen through earbuds with incredible sound quality and extended battery life; or use earbuds with a smaller form factor while still matching the previous generation’s playtime.<h2>Upping the pace with wireless tech</h2>Getting the heart beating a little faster is a path to mental and physical health improvements and wireless tech has transformed the experience. Advanced <a href="https://www.nordicsemi.com/News/2023/06/Casio-launches-new-Nordic-powered-watch-with-multiple-sports-support?utm_campaign=2021%20wevolver" rel="noopener noreferrer" target="_blank">smart watches</a> not only allow us to track exercise metrics, analyze workout data, and provide personalized fitness recommendations but can also keep track of the exercise’s impact on health indicators such as hear rate variability, sleep quality, blood oxygen levels, and stress.Early devices employed Bluetooth LE to connect to a smartphone app. The smartphone also formed a gateway to send the runner’s data to the Cloud. But a new generation of <a href="https://www.nordicsemi.com/News/2020/09/ProMOS-Technologies-employs-nRF9160?utm_campaign=2021%20wevolver" rel="noopener noreferrer" target="_blank">products</a> now employ <a href="https://www.nordicsemi.com/Products/Low-power-cellular-IoT?utm_campaign=2021%20wevolver" rel="noopener noreferrer" target="_blank">cellular connectivity</a> such that user data can be sent directly to the Cloud, without requiring a smartphone as a gateway. Cloud connectivity provided by cellular IoT devices such as Nordic’s nRF9160 SiP, which also incorporates GNSS, is particularly useful in situation where users fall or get lost because then the wearable can send the user’s location to emergency responders.E-bikes are encouraging millions of new riders to jump on to two wheels. The electric technology is frequently complemented by wireless. For example, the <a href="https://www.nordicsemi.com/News/2023/06/The-Xion-E-Bike-HMI-System-employs-nRF52840-SoC?utm_campaign=2021%20wevolver" rel="noopener noreferrer" target="_blank">Xion E-Bike HMI System</a> attaches to the handlebars of any e-bike. The product not only acts as a traditional display system for the bicycle so that the rider can view their riding metrics and the bike’s overall battery level, but it also allows users to select their desired assistance level. Moreover, because the Xion E-Bike HMI System is directly connected to the e-bike's battery, there’s no need to recharge it separately.The product employs Nordic nRF52840 SoC to send data, such as the rider’s speed and distance, to a paired smartphone. The Xion unit is also managed by the nRF52840’s Arm Cortex-M4 processor which provides the necessary computing power for all the device’s functionality.<h2>Getting wet with wireless tech</h2>Wireless tech is not just limited to enhancing running or walking; other sports ranging from skiing, soccer, golf, and tennis are benefiting too. And it’s not necessary to stay dry either, wireless tech also plays a role in the water. For example, Sweden-based technology company, Radinn has released a <a href="https://www.nordicsemi.com/News/2023/07/Radinn-jetboards-employ-the-nRF52840-SoC-to-provide-wireless-connectivity?utm_campaign=2021%20wevolver" rel="noopener noreferrer" target="_blank">range of electric jetboards</a> (motorized surfboards) for leisure watersports. Users can skim along at 60 km/hr and enjoy the ride for up to 45 minutes between charges.The fun is controlled by a wireless remote equipped with Nordic’s <a href="https://www.nordicsemi.com/products/nrf52840" rel="noopener" target="_blank">nRF52840</a> SoC. The board itself also hosts a Nordic-powered wireless module, which oversees the accelerometer and gyroscope sensors to provide rider data, such as speed and performance metrics, as well as impact detection. The module can also send the ride data to the Radinn app on the user’s smartphone for analysis and presentation.Time spent on hobbies and other relaxing activities can be incredibly rejuvenating and replenishing. And wireless tech is doing its bit to not only keep things interesting but also attract a whole new audience to traditional and not-so-traditional leisure activities.<hr>This article was first published on Nordic's&nbsp;<a href="https://blog.nordicsemi.com/getconnected" target="_blank" rel="nofollow" id="isPasted"></a><a href="https://blog.nordicsemi.com/getconnected?utm_campaign=2021%20wevolver" target="_blank" rel="nofollow">Get Connected Blog</a>. &nbsp;

The new iteration features groundbreaking silicon at its heart. The <a href="https://www.mouser.com/new/raspberry-pi/raspberry-pi-5-sbc/" target="_blank">Raspberry Pi 5</a> is a game-changer with a few new tricks up its sleeve.The Raspberry Pi Foundation has navigated countless challenges over the years, from production woes to supply chain disruptions. But their unwavering commitment to delivering computing innovation to all has brought us to this pivotal moment.<h2 dir="ltr">Introducing the Raspberry Pi 5: A Marvel of Custom Silicon</h2>The Raspberry Pi 5 is based on the Broadcom BCM2712, which houses a quad-core 2.4GHz 64-bit Arm® Cortex®-A76 processor. However, the standout component here is the RP1, a proprietary I/O controller crafted entirely in-house by the Raspberry Pi team. This custom chip assumes a pivotal role in furnishing USB 3.0, Ethernet, GPIO, MIPI display, and MIPI camera ports. The inclusion of the RP1 custom I/O chip not only adds stability to the Pi 5's manufacturing process but also optimizes power consumption by integrating only the most critical circuits into the chip.&nbsp;&nbsp;<iframe id="6567366c3a755eabfe69da44" width="250" class="specs-iframe" height="440" src="https://wevolver.com/iframe/specs/raspberry-pi-5-single-board-computer?iframe=true" frameborder="0" scrolling="no" data-gtm-yt-inspected-9="true" data-lf-form-tracking-inspected-kn9eq4roawkarlvp="true" data-lf-yt-playback-inspected-kn9eq4roawkarlvp="true" data-lf-vimeo-playback-inspected-kn9eq4roawkarlvp="true"></iframe>But the excitement doesn't stop there. Beyond custom silicon, the Raspberry Pi 5 introduces a four-lane PCIe 2.0 interface, streamlining high-speed peripheral connections. It also boasts Bluetooth® 5.0 with Bluetooth Low Energy, dual-band Wi-Fi®, and Gigabit Ethernet, granting users the flexibility to choose between wired and wireless connectivity. Moreover, the Pi 5 extends support for Power over Ethernet (PoE), enabling users to power the board via Ethernet, alongside a USB Type-C port for alternative power sources.&nbsp;While the board seamlessly integrates a real-time clock (RTC), the absence of an onboard battery necessitates using a networked time server to maintain time accuracy during power disruptions. Fortunately, users can power the RTC externally through a supercapacitor or small battery, ensuring precise timekeeping even in power outage scenarios.&nbsp;Power management receives an upgrade with the Renesas DA9091 power management IC, capable of supplying up to 20A to the BCM2712 for high-performance processing.

The new Arduino UNO R4 Wi-Fi board provides built-in Wi-Fi and Bluetooth communication as well as a 12×8 LED matrix display to give makers, hobbyists, and engineers an extremely versatile prototyping tool.


Getting to Know the Arduino UNO R4 Wi-Fi

In April 1981, The Washington Post&nbsp;reported that the U.S. supermarket chain, Giant Food Inc., was about to stop marking prices on individual items in its stores in a bid to reduce operating costs. If there was no consumer backlash, the report predicted, the rest of the industry would follow, as it did when the company was the first food retailer to introduce barcode scanners at its checkouts, spurring the spread of that technology across the country.Fast forward 40 years and individually priced items in supermarkets have long been consigned to history, with shelf pricing now the accepted norm. And it has, as Giant Food hoped, reduced operating costs for retailers that can stock as many as 50,000 different product lines. As recently as the 1990s, 7,000 product lines was considered average. Now technology is overhauling shelf labeling anew, and supermarkets will be the likely trailblazers once again.<h2>The beginning of the end for paper labels</h2>Electronic shelf labels (ESL) are connected, low-power &lsquo;e-paper&rsquo; display devices that can replace traditional paper labels and can display text, numbers, icons, lines, barcodes and pictures. They enable retailers to automatically update individual shelf price labels from a central point across multiple stores and branches&mdash;or in certain geographic locations&mdash;at the touch of a button. Comprised of a Cloud platform, access points or gateways, and wirelessly connected shelf labels, pricing commands can be sent from a web-based dashboard to store-located gateways, from which point commands are relayed to the smart labels.According to analyst ABI Research, by the end of last year, 788 million electronic shelf labels (ESL) had been installed globally. The number may seem significant, but with tens of billions of paper labels still on shelves, the technology has yet to make it mainstream, despite not really counting as a &lsquo;new&rsquo; technology. Primitive versions using liquid crystal displays that could display a price but nothing else have been around for some 30 years. There are a number of reasons the technology has yet to hit the big time, including market fragmentation, cost of deployment, concerns over interoperability, security, and a fear of obsolescence. Now this could be about to change.Earlier this year, the Bluetooth Special Interest Group (SIG), announced the release of the <a href="https://www.bluetooth.com/learn-about-bluetooth/use-cases/electronic-shelf-labels/?utm_campaign=2021%20wevolver" rel="noopener noreferrer" target="_blank">new wireless standard for the ESL market</a>, with the goal of making Bluetooth the standard protocol for ESL.&nbsp;The scalable, low-power, secure ESL standard (consisting of ESL Profile and Service specifications) has been developed by a working group comprised of a leading ESL vendor and enabling technology suppliers, and standardizes the process for message transmission between access points and ESLs. To do so it leverages feature enhancements introduced in the Bluetooth Core Specification Version 5.4, including Periodic Advertising with Responses (PAwR) and Encrypted Advertising Data (EAD).In general, PAwR and EAD are intended for one-to-many applications that involve a large number of devices (tags) receiving and transmitting small amounts of data from and to an access point, that accept longer latencies (e.g. 2 seconds) in exchange for extended battery life. Together, they enable connectionless, bidirectional, secure communication with thousands of very low-power end nodes in a star topology, essential in a retail ESL application where many thousands of labels could be required to cover all of the items stocked. For a technical deep dive on ESL, PAwR and EAD see <a href="https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/whats-new-in-bluetooth-v5-4-an-overview?utm_campaign=2021%20wevolver" rel="noopener noreferrer" target="_blank">What&#39;s new in Bluetooth v5.4: An overview</a>.<h2>Dynamic, efficient pricing operations</h2>If the introduction of the standard has the intended effect on the retail industry and ESL becomes widespread, retailers are set to benefit in several ways. Updating paper price labels requires staff to change thousands of tags every week. It&rsquo;s not only a lot of labor to do very little, it also takes time and is prone to error, and inaccurate pricing on shelves even for a short time can cost grocery retailers profit. ESL eliminates the manual process and at the same time enables dynamic pricing strategies allowing retailers to adjust pricing based on stock levels, demand, and market conditions.Standardization is key here to ensure interoperability, security and to allow retailers to have systems that can be installed and easily maintained over a long lifespan. At the same time, Bluetooth can also be leveraged to keep tags updated with the latest firmware, using Over-The-Air Device Firmware Updates from the gateway itself.Moreover, by using Bluetooth as the protocol, some ESL systems can mix and match with other Bluetooth technologies, such as Bluetooth Direction Finding for a quick positioning, enabling staff to quickly and easily identify the specific location of individual product lines across the store. This is particularly beneficial to staff responsible for picking and replenishing stock. Paired with Wi-Fi-connected shelf cameras and Cloud-based AI models, savvy retailers are also remotely monitoring stock to ensure shelves are well stocked and only replenished when necessary.The smart labels can also be used as beacons for marketing to consumers in close proximity via compatible smartphone apps, at the same time allowing retailers to gather insights into customer behavior to provide improved shopping experiences, personalized marketing, and to increase conversion rates in store.<h2>Widescale adoption looms</h2>Nordic Semiconductor, as the market leader in Bluetooth LE, has already introduced the PAwR and EAD features as standard in its qualified Bluetooth 5.4 SoftDevice Controller in the <a href="https://www.nordicsemi.com/Products/Development-software/nRF-Connect-SDK?utm_campaign=2021%20wevolver" rel="noopener noreferrer" target="_blank">nRF Connect SDK</a>, and companies developing ESLs can start working with this technology today thanks to the pre-release reference example (both gateway and tags) now available on request by opening a <a href="https://devzone.nordicsemi.com/support/add?utm_campaign=2021%20wevolver" rel="noopener noreferrer" target="_blank">private ticket on DevZone</a> or by <a href="https://www.nordicsemi.com/About-us/Contact-Us?utm_campaign=2021%20wevolver" rel="noopener noreferrer" target="_blank">contacting Nordic sales</a>.Nordic&rsquo;s SoCs meet the ultra low power requirements of ESLs where the number of tags involved prohibits even infrequent battery changes, while the Flash and RAM allocation ensures they can store the volume of information required to implement a fully-featured ESL system. Both the nRF53 Series and several of the nRF52 Series SoCs also support Direction Finding, enabling optimized order picking and replenishment functionality.The announcement of the standard has provided retailers with the impetus to commit to this technology. ABI Research claims 185 million ESL units were shipped last year, and that by 2028 annual shipments will reach 558 million, with a total installed base of some three billion ESLs. For example, Fortune 500 leading light and U.S. retail behemoth Walmart has entered an agreement to roll out 60 million digital shelf labels across 500 locations over the next 12 to 18 months. Others will follow.<hr>This article was first published on Nordic&#39;s <a href="https://blog.nordicsemi.com/getconnected" target="_blank" rel="nofollow" id="isPasted"></a><a href="https://blog.nordicsemi.com/getconnected?utm_campaign=2021%20wevolver" target="_blank" rel="nofollow">Get Connected Blog</a>. &nbsp;

Electronic shelf labels (ESL) are connected, low-power ‘e-paper’ display devices that can replace traditional paper labels and can display text, numbers, icons, lines, barcodes and pictures. They enable retailers to automatically update individual shelf price labels from a central point across multiple stores and branches—or in certain geographic locations—at the touch of a button.
