The Raspberry Pi Debug Probe is an all-in-one USB-to-Debug kit that provides all the necessary hardware and cables for easy, solderless plug-and-play debugging.
It features both a processor serial debug interface (the Arm Serial Wire debug interface by default, but other interfaces can be supported), and an industry-standard UART interface. Both interfaces use the Raspberry Pi's 3-pin debug connector, as described in the Raspberry Pi's 3-pin debug connector specification (see datasheets).
The Raspberry Pi Debug Probe is a kit that includes the debug probe hardware in its own plastic case along with a USB cable and three types of debug cables, covering the vast majority of debug use cases. It is designed to simplify debugging and programming of Raspberry Pi Pico and RP2040 with a range of host platforms including Windows, Mac and typical Linux computers where you do not have a GPIO header to connect directly to the serial UART or Pico (SWD port).
Although the Debug Probe is designed for use with Raspberry Pi products, it provides standard UART and CMSIS DAP interfaces over USB, so it can also be used to debug any Arm-based microcontroller that provides a SWD port with 3V3 I/O or even just provide it as a USB-to-UART cable. It works with OpenOCD and other tools that support CMSIS-DAP.
The Debug Probe is based on the Raspberry Pi Pico hardware and runs the open source Raspberry Pi Picoprobe software. The firmware is updated in the same way as the Raspberry Pi Pico firmware, so it is easy to keep the device up to date with the latest firmware or use custom firmware.
