## Description

The PiProbe is a simple 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 regular *Dupont* style 0.1" pitch cables 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 for example.

Documentation for downloading openocd and using the PiProbe can be found in the official [Pico Getting Started Guide](https://datasheets.raspberrypi.com/pico/getting-started-with-pico.pdf) *8.1. Debugging your project* section.

The GPIO pins of the Raspberry Pi 40-pin header are connected as 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 |

**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 [Pico Getting Started Guide](https://datasheets.raspberrypi.com/pico/getting-started-with-pico.pdf).
- The PicoProbe Sled to used to debug another Pico from a computer (Windows/MacOX/Linux) using the PicoProbe Sled as a debug tool providing the SWD and UART interfaces. As described in section *Appendix A: Using Picoprobe* of [Pico Getting Started Guide](https://datasheets.raspberrypi.com/pico/getting-started-with-pico.pdf)
- Connecting the SWD connectors on the *PiProbe* and *PicoProbe Sled* together will not allow you to debug the Pico on the *PicoProbe Sled*.

**UART/SWD Cables are not included** - see the our other product where you can order the lengths as required.
