If you’re looking for a development board that also acts as a debugger for your Raspberry Pi 5 or ARM Microcontroller, look no further!

This little device has been built around the Raspberry Pi RP2350 and is compatible with standard CMSIS-DAP debugging tools like OpenOCD.

The device attaches to the Raspberry Pi 5/Pico H/WH 3-pin debug connector for debugging and can be used to debug most ARM-based microcontrollers. A range of cables are included to allow you to connect to debug ports or directly to IO pins.

The board has three ports, SWD, UART, and I2C, making it much easier to set up debugging and anything else you need to connect to. To monitor progress/output, there’s a vibrant 1.14″ IPS LCD Display with 240 x 135 resolution and 65K colour. For your storage needs, there is an SD card slot and 16MB of flash memory.
