Overview
Feather is the new development board from Adafruit, and like it's namesake it is thin, light,
and lets you fly! We designed Feather to be a new standard for portable microcontroller
cores.
This is the Adafruit Feather M0 Bluefruit - our take on an 'all-in-one' Cortex M0+ Arduino-
compatible + Bluetooth Low Energy with built in USB and battery charging. Its an Adafruit
Feather M0 with a BTLE module, ready to rock! We have other boards in the Feather family,

Bluetooth Low Energy is the hottest new low-power, 2.4GHz spectrum wireless protocol. In
particular, its the only wireless protocol that you can use with iOS without needing special
certification and it's supported by all modern smart phones. This makes it excellent for use in
portable projects that will make use of an iOS or Android phone or tablet. It also is supported
in Mac OS X and Windows 8+
