Feather is the flagship development board from Adafruit, and like its namesake, it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores.

This is theAssembled Adafruit Feather HUZZAH ESP8266with headers our take on an all-in-one ESP8266 WiFi development board with built-in USB and battery charging and ready to go immediately! Its an ESP8266 WiFi module with all the extras you need, ready to rock!

At the Feather HUZZAHs 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. We wired up a USB-Serial chip that an uploads 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, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You dont 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.

Features:

1. ESP8266 v1.1 @ 80MHz with 3.3V logic/power

6. 9 x GPIO pins can also be used as I2C and SPI
7. 1 x analog inputs 1.0V max
8. Built-in 100mA LiPoly charger with charging status indicator LED, can also cut a trace to disable the charger
9. Pin #0 red LED for general purpose blinking. Pin #2 blue LED for boot loading debug & general purpose blinking
10. Power/enable pin
11. Reset button
