## What it is
Firmware source and binaries for the Raspberry Pi Debug Probe, an RP2040-based USB-to-SWD/UART debugging accessory. It can also run on a Raspberry Pi Pico or Pico 2 to turn them into debug probes.

## Use cases
- debug rp2040 microcontrollers over swd
- turn a raspberry pi pico into a debug probe
- usb to uart serial bridge for microcontrollers
- flash and debug pico boards from openocd
- build custom debug probe firmware

## When to choose
- you need SWD debugging or UART access for RP2040/RP2350 boards
- you want to repurpose a Pico as a CMSIS-DAP style debug probe
- you want to modify or study debug probe firmware

## When to avoid
- you need a debugger for non-Raspberry-Pi architectures without CMSIS-DAP support
- you want a graphical debugging tool rather than firmware
- you need JTAG rather than SWD

## Facets
- artifact type: application
- maturity: active
- function: embedded, developer-tools, testing
- domain: embedded-systems, developer-tools, hardware
- platform: embedded, cross-platform
- tags: rp2040, debug-probe, swd, cmsis-dap, firmware, uart, picoprobe, microcontroller
