RaspberryPi Pico to UNO FlexyPin Adapter

Overview

Raspberry Pi Pico to Uno FlexyPin Adapter is a converter-PCB to Arduino UNO form-factor from Raspberry Pi Pico that is released in Open Source Hardware. This board design to use with FlexyPin. The FlexyPin holds Pico and contacts to castellated through-hole. With simple soldering, it can also be used as a board to convert the RapsberryPi Pico o the Arduino UNO form factor.

Programming

Set -DSHIELD=rpi_pico_uno_flexypin when you invoke west build. This shield is just a converter, so it is usually used with other Arduino shield.

For example,

# From the root of the zephyr repository
west build -b rpi_pico samples/net/wifi -- -DSHIELD='rpi_pico_uno_flexypin;esp_8266_arduino'
