Raspberry Pi Debug Probe Kit for Pico

The Raspberry Pi Debug Probe is an all-in-one USB to serial debug and UART bridge.

Powered by an RP2040, it provides the necessary hardware and cabling to support “plug and play” debugging of Raspberry Pi Pico and other microcontroller and microprocessor-based platforms.

Board Overview of the Debug Probe

Featuring a USB to two-wire serial debug bridge and a USB to UART bridge, the Debug Probe makes it easy to use devices such as Raspberry Pi Pico with a range of host platforms including PC, Mac, and typical Linux computers.

While designed for use with Raspberry Pi products, the debug probe also provides standard UART and CMSIS-DAP interfaces over USB, so it can also be used to debug any Arm-based microcontroller that provides an SWD port with 3V3 I/O, or even just as a USB-to-UART cable. It works well with OpenOCD and other tools that support CMSIS-DAP.

The Debug Probe is based on Raspberry Pi Pico hardware and runs the open-source Raspberry Pi Picoprobe software. The firmware is updated in the same way as Raspberry Pi Pico firmware, so it is easy to keep the unit up to date with the latest firmware, or to use custom firmware.
