Description

The Adafruit Feather is a thin, lightweight, and portable Arduino compatible development board from Adafruit. At the Feather's heart is at ATmega32u4 clocked at 8 MHz and at 3.3V logic. This chip has 32K of flash and 2K of RAM, 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 can also act like a mouse, keyboard, or USB MIDI device and is well supported in the Arduino Development Environment (IDE). Just plug it in using a USB micro Cable and you are good to go!

To make it easy to use for portable projects, there is a connector for a 3.7V Lithium polymer battery and built in battery charging. You don't need to use a battery with the Feather, it will run just fine straight from the micro USB connector, but it is awfully handy having it built right into the board. The Feather will automatically switch over to USB power when its available. The battery is tied through a voltage divider to an analog pin, so you can measure and monitor the battery voltage without any additional circuitry.

The Feather also has a little space left over at the bottom so adding sensors or other circuits is nice and easy!
