The Raspberry Pi Debug Probe is an inexpensive, all-in-one USB-to-debug to serial debug and UART bridge that provides all the necessary hardware and cables for easy, solderless, plug-and-play debugging. 

The Raspberry Pi Debug Probe is provided as a kit, containing the probe hardware in a plastic case, and a set of cables: a USB cable, and three different types of debug cable to cover the vast majority of use cases.

It provides:

• A USB to Serial Wire Debug (SWD) bridge
• A generic USB serial adapter
• Cables to connect to a host computer, and to the debug target

While it has been designed primarily for Raspberry Pi Pico, and other RP2040-based targets, the Debug Probe provides standard CMSIS-DAP debug and UART interfaces over USB; it can therefore be used to debug other targets (that have an SWD port with 3V3 I/O), or simply as a cost-effective USB-to-UART cable.
