The Raspberry Pi Debug Probe is a perfect plug-and-play connection debugging solution, ideal for the Raspberry Pi Pico, the XIAO RP2040, other RP2040-based microcontrollers and microprocessor-based platforms. It combines a USB interface with its own serial debug connector and an industry-standard UART interface, both using a small keyed 3-pin debug connector that was released for the following standard.

It uses a small keyed 3-pin debug connector designed to operate with one unidirectional clock pin and a bidirectional data I/O pin. This arrangement can support, for example, ARM’s Serial Wire Debug (SWD) system or things like cJTAG.

It combines a USB interface with its own serial debug connector and an industry-standard UART interface. Although the Debug Probe is primarily designed for use with Raspberry Pi debugging targets, it provides standard CMSIS-DAP debug and UART interfaces over USB. In other words, it can be used to debug other targets or simply as a cost-effective USB-UART cable.

Features

• All-in-one Debug Probe: Combines a USB interface with its own serial debug connector and an industry-standard UART interface.
• Plug and Play: Use the 3-pin debug connector to work with a single unidirectional clock pin and a bidirectional data I/O pin.
• Supports multiple debug targets: In addition to the Raspberry Pi Pico and RP2040, it supports platforms using other microcontrollers and microprocessors.
• Raspberry Pi production quality: Based on the Raspberry Pi Pico hardware design and uses the open-source PicoProbe software.
