Arduino-Pico
This is the documentation for the Raspberry Pi Pico Arduino core, Arduino-Pico. Arduino-Pico is a community port of the RP2040 (Raspberry Pi Pico processor) to the Arduino ecosystem, intended to make it easier and more fun to use and program the Raspberry Pi Pico / RP2040 based boards.
This Arduino core uses a custom toolset with GCC 10.3 and Newlib 4.0.0 and doesn’t require any system-installed prerequisites.
