Description
Feather is the flagship development board from Adafruit and like its namesake it is thin light and lets you fly! Feather was designed to be a new standard for portable microcontroller cores.
This is the Assembled Adafruit Feather HUZZAH ESP8266 (Headers not included) Adafruit’s take on an ‘allinone’ 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 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 easytorun Internet of Things core. The USBSerial chip is wired up for an upload code at a blistering 921600 baud for fast development time. It also has autoreset so no noodling with pins and reset button pressings.
To make it easy to use for portable projects there’s a connector for any 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.
