Feather M0 Express CircuitPython ATSAMD21 Cortex

This one of the special Feather from Adafruit. This one is designed for CircuitPython! The CircuitPython is a noob oriented style of MicroPython. It is small but it has the full feature of Python programming designed for circuitry and electronics.

Please take note that the CircuitPython needs to be loaded. We have a full guide on that. 

The heart of the Feather M0 is an ATSAMD21G18 ARM Cortex M0+ processor meaning you can also use your Arduino IDE.
