Adafruit Metro M0 Express - Designed for CircuitPython
CircuitPython, Arduino IDE or even MakeCode with this Metro M0
by lady ada
Metro is our series of microcontroller boards for use with the Arduino IDE. This new Metro board looks a whole lot like our original Metro 328, but with a huge upgrade. Instead of the ATmega328, this Metro features a ATSAMD21G18 chip, an ARM Cortex M0+. It's our first Metro that is designed for use with CircuitPython! CircuitPython is our beginner-oriented flavor of MicroPython - and as the name hints at, its a small but full-featured version of the popular Python programming language specifically for use with circuitry and electronics.
