  • Adafruit Feather HUZZAH with ESP8266 WiFi

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

    This is the Adafruit Feather HUZZAH ESP8266 - Adafruit's take on an 'all-in-one' ESP8226 WiFi development board with built-in USB and battery charging. It's an  ESP8266 WiFi module with all the extras you need, ready to rock! Adafruit has other boards in the Feather family, check'em out here.

    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. Adafruit 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, Adafruit added a connector for any of Adafruit's 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 it's available.

    Here're some handy specs! Like all Feather 32u4's you get:

    • 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 baud rate 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 analogue 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 boot loading debug & general purpose blinking
    • Power/enable pin
    • 4 mounting holes
    • Reset button

    Comes fully assembled and tested, with a USB interface that lets you quickly use it with the Arduino IDE or NodeMCU Lua. (It comes preprogrammed with the Lua interpreter) They also toss in some header so you can solder it in and plug into a solderless breadboard. Lipoly battery and USB cable not included.
