Arduino-Pico

Raspberry Pi Pico Arduino core, for all RP2040 and RP2350 boards

This is a port of Arduino to the RP2040 (Raspberry Pi Pico processor) and RP2350 (Raspberry Pi Pico 2 processor). It uses the bare Raspberry Pi Pico SDK and a custom GCC 16.1/Newlib 4.6 toolchain and supports ARM and RISC-V cores.

Installing via Arduino Boards Manager

Windows-specific Notes

Please do not use the Windows Store version of the actual Arduino application because it has issues detecting attached Pico boards. Use the "Windows ZIP" or plain "Windows" executable (EXE) download direct from https://arduino.cc. and allow it to install any device drivers it suggests. Otherwise the Pico board may not be detected. Also, if trying out the 2.0 beta Arduino please install the release 1.8 version beforehand to ensure needed device drivers are present. (See #20 for more details.)

Linux-specific Notes

Installing Arduino using flatpak (often used by "App Stores" in various Linux distributions) will mean it has restricted access to the host. This might cause uploads to fail with error messages such as the following:

Scanning for RP2040 devices
...
No drive to deploy.

If you encounter this, you will need to either install Arduino in a different manner, or override the flatpak sandboxing feature using the following command, then restarting Arduino.

flatpak override --user --filesystem=host:ro cc.arduino.IDE2

Installation

Open up the Arduino IDE and go to File->Preferences.

In the dialog that pops up, enter the following URL in the "Additional Boards Manager URLs" field:
