[3DMakerWorld] Adafruit Feather M0 Express - Designed for CircuitPython

Description

Key Features:
ATSAMD21G18 @ 48MHz with 3.3V logic/power
256KB of FLASH + 32KB of RAM
Easy reprogramming
Built in USB so it has USB-to-Serial program & debug capability built in with no need for an FTDI-like chip
This is the first Feather that is
specifically
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.
That doesn't mean you cant
also
use it with Arduino IDE! This chip comes with built in USB so it has USB-to-Serial program & debug capability built in with no need for an FTDI-like chip. The Feather M0 Express uses the extra space left over to add a Mini NeoPixel, 2 MB SPI Flash storage and a little prototyping space. You can use the SPI Flash storage like a very tiny hard drive. When used in CircuitPython, the 2 MB flash acts as storage for all your scripts, libraries and files. When used in Arduino, you can read/write files to it, like a little datalogger or SD card, and then with our helper program, access the files over USB.
