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

This is the Adafruit Feather HUZZAH ESP8266 - our take on an 'all-in-one' 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! We have 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. We wired up a high-quality SiLabs CP2104 USB-Serial chip that 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. 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, 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!

  • 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 speedy 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 that lets you quickly use it with the Arduino IDE or NodeMCU Lua. (It comes preprogrammed with the Lua interpretter) We also toss in some header so you can solder it in and plug into a solderless breadboard. Lipoly battery and USB cable not included (but we do have lots of options in the shop if you'd like!)

  1. Review by Nick verified purchaser

    For those getting started with IoT, this product will help you get up and running and developing your sketches. Easy to flash with all you need on the board. Once you’ve developed your sketch, you may need another board for low power consumption like an ESP-xx as the other elements on the board take a bit of juice but very hand for development or when batteries are not an issue. Great service from Core as usual and swift delivery. (Posted on 3/01/2018)

  2. Review by Jon verified purchaser

    Super smart little board. Followed a few tutorials and had my project done in no time. (Posted on 29/12/2017)

  3. Review by Victor verified purchaser

    I have spent quite a bit of time trying to get off the ground with ESP8266 ESP01. While being the cheapest option, Its just a lot to take in to begin with. I didn't have the time to learn Chinese, so, I shelved it for a while.
    So, along came Adafruit with much more features and a bunch of instructions to get me started. (Posted on 29/12/2017)

  4. Review by Jim verified purchaser

    I'm pretty new to Arduino and this was a great board to work with. Very happy with it. It runs a weather station I've installed in the back garden (temperature, humidity and pressure sensors) with a 2000mAh LiPo battery. It runs in deep sleep mode and wakes every 15 min, measures the weather and battery level and reports over the WiFi to a local PC where the data is logged to a MySQL database. It also sends its data to Blynk so I can track things from my phone :-). In this mode, the battery only needs charging every 2 weeks.

    What's next? Adding a solar panel so it runs forever :-) (Posted on 27/11/2017)

  5. Review by Paul verified purchaser

    This is a quality development board and a step up from my much-loved Arduinos. With ESP wifi, 4Mb of flash memory and built-in battery charging/backup, these are a great platform to develop IOT devices, especially if you are already familiar with the Arduino IDE. Adafruit (and others) have some great guides and examples on the web to make that transition smooth. There is only a single "analog" input, limited to 1v, but that can be worked around with an i2c adc breakout. Some Arduino libraries work a little differently on this board but the differences are well documented. I think these are my new "go to" board. (Posted on 21/08/2017)

  6. Review by Chris verified purchaser

    I'm a bit of a newbie with Feather, but if you're familiar with the Arduino IDE you shouldn't have any problem with Feather. I like the range and the size. The built-in WiFi and LiPo charger is really convenient. (Posted on 29/06/2017)

  7. Review by Andrew verified purchaser

    Have only played with this for a short time, but getting up and running could not have been simpler. Installed MicroPython quite easily via guides available on Adafruit.
    Great price, quick postage. (Posted on 25/10/2016)

  8. Review by Frank verified purchaser

    Awesome product! Kind of like an Arduino with built-in WiFi, LiPo charger and lots of memory. I haven't touched my Uno or Nano since I started using this board. So many potential uses for this thing!

    Pros - very small, lightweight. Can be programmed with Arduino IDE if preferred. Lot's of features for such a small package and low cost. Excellent tutorials available.

    Cons - not suitable for beginners. Pins have multiple uses which can be a little confusing. 3.3v logic (but some pins are 5v tolerant). Just takes a bit of time/reading to get on top of it. (Posted on 10/03/2016)
