Note: This module comes with loose headers, so soldering is required. please take EXTRA PRECAUTION while doing soldering works. We don't want you to get burns.
Feather is the new development board from Adafruit, and like its namesake it is thin, light, and lets you fly! Adafruit designed Feather to be a new standard for portable microcontroller cores.
This is the Adafruit Feather HUZZAH ESP8266 - 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!
Note: USB micro B cable is NOT INCLUDED in the package. You will need a USB micro B cable to power and to program this board, so grab this cable here if you don't have one.
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. Adafruit wired up a high-quality SiLabs CP2104 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. The CP2104 has better driver support than the CH340 and can do very high speeds without stability issues.
To make it easy to use for portable projects, a connector for any of our 3.7V Lithium polymer batteries and built in battery charging are added. 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.
