RP2040 Debug Probe

Raspberry Pi Debug Probe is a complete plug-and-play interface debug solution perfect for Raspberry Pi Pico, XIAO RP2040, other RP2040-based microcontrollers, and microprocessor-based platforms. It bridges the USB interface to a dedicated serial debug interface and industry-standard UART interface, both of which use a small, keyed, 3-pin debug connector, published for the next standard.

It applies small, keyed, 3-pin debug connectors, which is designed to work with a single unidirectional clock pin and a bidirectional data I/O pin. This arrangement can support ARM’s Serial Wire Debug (SWD) or things like cJTAG, for example.

It bridges the USB interface to a dedicated serial debug interface and industry-standard UART interface. While it has been designed primarily for use with Raspberry Pi debug targets, the Debug Probe provides standard CMSIS-DAP debug and UART interfaces over USB. That is, it can be used to debug other targets, or simply as a cost-effective USB-to-UART cable.
