More info


The Feather is the new development card developed by Adafruit and as its name suggests, Feather pen in English means, it's small, light and can you raise! It was designed to establish a new standard of small microcontroller.

This version of the Feather card has an area of prototyping and integrated management integrated with a micro-USB connector battery charge.

It is composed of a heart to the ATmega32u4 clocked at 8 MHz controller database. This circuit has 32KB of Flash and 2KB of RAM and a built-in USB stack which allows to program USB directly and even emulate a keyboard, a mouse, or even a MIDI enables.

In order to realize mobile montages, this has to a built-in JST connector card dedicated to batteries Lithium polymer 3, 7V with a charging circuit. If you do not need battery, simply feed it through the micro-USB connector. The Feather card will automatically switch between USB power and the battery if needed.
