The PiProbe is an adaptor with protection resistors used to debug a Raspberry Pi Pico/RP2040 microcontroller using OpenOCD from a Raspberry Pi computer.

On the top side of the board, there are two 3-pin connectors:

  • SWD to debug the ARM core and
  • UART for a serial connection you can connect to the target device

On the underside of the board, there's a 9-pin 0.1" header which replicates the SWD and UART interfaces and adds both 5V and 3.3V power. The SWD/UART pins on the 9-pin connector can be used with jumper wires and a breadboard for example.

The GPIO pins are 3.3V only but the 5V output could be used to power a Pico you're debugging. Documentation for downloading OpenOCD and using the PiProbe can be found in the official Pico Getting Started Guide 8.1. Debugging your project section.

Raspberry Pi, Raspberry Pi Pico and cables not included 

Please Note

  • The PiProbe is used to debug a Pico from a Raspberry Pi directly. As described in section 8.1. Debugging your project of the Pico Getting Started Guide.
  • Connecting the SWD connectors on the PiProbe and PicoProbe Sled (available separately) together will not allow you to debug the Pico on the PicoProbe Sled.



The GPIO pins of the Raspberry Pi 40-pin header are connected below:

Raspberry Pi GPIO 3-pin/9-pin name Usage
GPIO25 SC Connect to target SC (SWD Clock)
GPIO24 SD Connect to target SD (SWD Data)
GPIO14 TX Connect to target UART RX
GPIO15 RX Connect to target UART TX

Package Contents

  • 1x PiProbe board (assembled)
