Description

The Adafruit Feather M0 Bluefruit LE is Adafruit’s take on an all in one Arduino compatible microcontroller with built in Bluetooth LE and built in battery charging. Basically, think of this as an Adafruit Feather M0 with a fancy Bluetooth LE module.

Bluetooth Low Energy is a low-power 2.4GHz spectrum wireless protocol. It is particular popular because it’s 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+.

At the Feather M0’s heart is an ATSAMD21G18 ARM Cortex M0 processor, clocked at 48 MHz and at 3.3V logic. This chip has a whopping 256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x as much)! 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.

To make it easy to use for portable projects, Adafruit has added a connector for a 3.7V Lithium polymer battery and built in battery charging. The battery isn’t necessary for operation, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. To keep tabs on the battery, Adafruit has also connected one of the analog pins through a voltage divider to the battery input.
