Key Features:
- ESP8266 WiFi module with all the extras you need
- CP2104 USB-Serial converter onboard with 921600 max baudrate for uploading
- Auto-reset support for getting into bootload mode before firmware upload
- Built in battery charging means you don't need a battery
This is the Adafruit Feather HUZZAH ESP8266 - an 'all-in-one' ESP8266 WiFi development board with built in USB and battery charging. 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. We wired up a USB-Serial chip that an 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, 3.7V Lithium polymer battery and built in battery charging means 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.
