Feather is the new development board from Adafruit, and like its namesake it is thin, light, and lets you fly (in a metaphorical, technological sense!) The Feather is designed to be a new standard for portable microcontroller cores.
This is the Adafruit Feather HUZZAH ESP8266 - Adafruit's take on an 'all-in-one' ESP8266 WiFi development board with built in USB and battery charging. Its an ESP8266 WiFi module with all the extras you need, ready to rock! We have other boards in the Feather family, check'em out here.
At the Feather HUZZAH's heart is an ESP8266 WiFi microcontroller clocked at 80 MHz and at 3.3V logic. This microcontroller contains a Tensilica chip core as well as a full WiFi stack. You can program the microcontroller using the Arduino IDE for an easy-to-run Internet of Things core. It has a USB-Serial chip that can upload code at a blistering 921600 baud for fast development time. It also has auto-reset, so no noodling with pins and reset button pressings.
To make it easy to use for portable projects, it has a connector for any of Adafruit's 3.7V Lithium polymer batteries and built in battery charging. You don't need a battery, 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.
Here's some handy specs!
Comes fully assembled and tested, with a USB interface that lets you quickly use it with the Arduino IDE or NodeMCU Lua. (It comes preprogrammed with the Lua interpreter). This version comes pre-soldered with Feather stacking headers! Click here for the un-soldered version. Lipoly battery and USB cable not included (but we do have lots of options in the shop if you'd like!)
