Adafruit Feather HUZZAH with ESP8266 WiFi with Assembled Headers

(With Headers Installed)

Feather is the flagship development board from Adafruit, and like its namesake, it's thin, light and lets you fly! Adafruit designed the Feather to be a new standard for portable microcontroller cores.

This version has the pin headers pre-installed and it an 'all-in-one' ESP8266 WiFi development board with built in USB and battery charging and ready to go out-of-the-box!

At the core of the Feather HUZZAH is an ESP8266 WiFi microcontroller clocked at 80 MHz and at 3.3V logic. This MCU 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. (You may need to update your board list using the Board Manager option in the Arduino IDE.) The USB-Serial chip 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.

To make it easy to use for portable projects, there is a connector for common on most 3.7V lithium polymer batteries and built in battery charging circuit. You don't need a battery, for it will run just fine straight from the micro USB connector. If you do have a battery, you can take it on the go and plug in the USB to recharge. The Feather will automatically switch over to USB power when it's available.

Features

  • Measures 2.0" x 0.9" x 0.28" (51mm x 23mm x 8mm) without headers soldered in
  • Light as a (large?) feather - 9.7 grams
  • ESP8266 @ 80MHz with 3.3V logic/power
  • 4MB of FLASH (32 MBit)
  • Built in WiFi 802.11 b/g/n
  • 3.3V regulator with 500mA peak current output
  • CP2104 USB-Serial converter onboard with 921600 max baudrate for uploading
  • Auto-reset support for getting into bootload mode before firmware upload
  • 9 x GPIO pins - can also be used as I2C and SPI
  • 1 x analog inputs 1.0V max
  • Built in 100mA LiPoly charger with charging status indicator LED, can also cut a trace to disable the charger
  • Pin #0 red LED for general purpose blinking. Pin #2 blue LED for bootloading debug & general purpose blinking
  • Power/enable pin
  • 4 mounting holes
  • Reset button
Comes fully assembled and tested with a USB interface (micro-USB) that lets you quickly use it with the Arduino IDE or NodeMCU Lua (it comes preprogrammed with the Lua interpreter). This version of the board has also been pre-soldered, so you can plug it right into a solderless breadboard. See p/n: 2240083 for the unassembled version. Lipoly battery and USB cable not included.
