- CP2104 USB-Serial converter onboard with 921600 max baudrate for speedy uploading
- Auto-reset support for getting into bootload mode before firmware upload
- Built in 100mA LiPoly charger with charging status indicator LED, can also cut a trace to disable the charger
- Programmable using the Arduino IDE for an easy-to-run Internet of Things core
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 (clocked at 80 MHz and at 3.3V logic) with all the extras you need! This microcontroller contains a Tensilica chip core as well as a full WiFi stack. A high-quality SiLabs CP2104 USB-Serial chip that 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. 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, 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.
