It provides a flexible development environment along with the ability to create code that is power-efficient while cutting down on debugging time. The breakout board utilizes the latest version of MPLAB X Integrated Development Environment (IDE), to debug and program with a powerful and easy-to-use graphical user interface. In-circuit emulator breakout boards for MPLAB ICE 4 are best suited for usage with specialty connections, custom targets, and CI/CD systems.

Microchip Technology MPLAB ICE 4 Breakout Board Features  

The MPLAB ICE 4 in-circuit emulator connects to a host PC using a SuperSpeed USB 3.0 interface and wireless connectivity options. For programming, debugging, and other purposes, users can enable wireless connectivity to the tool by using Ethernet or Wi-Fi access point interfaces. The MPLAB ICE 4 in-circuit emulator is connected to adapter boards designed for supported device communication on one end and the target via a high-speed 40-pin robust edge rate cable assembly on the other.

The breakout board has a single row of 20 pins, which can be used to connect to the MPLAB ICE 4's JTAG connector. This makes it easy to connect the breakout board to the MPLAB ICE 4, even in lesser spaces. The pins on the breakout board are labeled with their corresponding JTAG signal names. Users can identify the pins connected to the signals, which makes troubleshooting problems easy. 

The breakout board is powered by a 9V DC wall-mount power supply. This allows the target device to power up using MPLAB ICE 4. This product supports a wide range of target devices with voltages from 1.2V to 5.5V. It also contains professional-grade safety features to enhance productivity:

The in-circuit emulator is used to connect UART signals for use with CI/CD containers. It is swift for users to automate the testing and deployment of their applications. Users can use CI/CD wizard to set up Jenkins and Docker on the latest version of MPLAB X IDE v6.00. It is easy to access trace signals and connect Data Gateway Interface (DGI) serial peripherals, using the breakout board. This can be useful for debugging and troubleshooting problems in applications.

The In-Circuit emulator breakout board has a comprehensive debug functionality, that supports multiple breakpoints, stopwatch and source code file debugging, and selectable pull-up/pull-down option to the target interface. Users can enhance their productivity with hassle-free maintenance and upgrades. The latest version of MPLAB X IDE can be downloaded to update the MPLAB ICE 4 in-circuit emulator's files. Developers and hobbyists who are looking for a way to connect the MPLAB ICE 4 to their target devices can use it. 


MPLAB ICE 4 Breakout Board is suitable for applications, utilizing specialty connections, custom targets, and CI/CD systems. It is best used to debug and troubleshoot applications, program target devices, test applications, and educate students about debugging, programming, and testing.
