Description

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 a Wifi ESP8266 controller with a management integrated with a micro-USB connector battery charge.

It is composed of a heart at base of the controller ESP8266 clocked to 80 MHz. You can program this microcontroller directly under the Arduino IDE thanks to a built-in USB/serial converter quick to 921600 baud, ideal to win at the time of development and with Automatic Reset.

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.
