Adafruit Metro Zero Dev Board SAMD21

The Metro is a series of microcontroller boards for use with the Arduino IDE. This new Metro M0 Express board looks a whole lot like the original Metro 328, but with a huge upgrade. Instead of the ATmega328, this Metro features a ATSAMD21G18 chip, an ARM Cortex M0+. It's the first Metro that is designed for use with CircuitPython! CircuitPython is a 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.

Not only can you use CircuitPython, but the Metro M0 is also usable in the Arduino IDE.
