Feather is the new development board from Adafruit and like its namesake it is thin light and lets you fly!Feather is designed to be a new standard for portable microcontroller cores. This is the Adafruit Feather HUZZAH ESP8266 our take on an ‘allinone’ 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! 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. We wired up a USBSerial chip that 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 we added a connector for any of our 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!
