Adafruit Feather HUZZAH with ESP8266 WiFi

by Adafruit

This is the Adafruit Feather HUZZAH ESP8266 - Adafruit's 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 progam 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, Adafruit added a connector for any of their 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 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) Adafruit also toss in some header so you can solder it in and plug into a solderless breadboard. Lipoly battery and USB cable not included

I've been using these... and the similar Sparkfun *DEV* Thing (note that there is a SF *Dev* thing, and a similar "Dec-less" thing... each have their merits) for several years now. Mostly as Arduservers... a devices attached to LANs at two different houses in different countries. Either set of Arduservers can be accessed with any web browser from anyplace in the world. The report, via a webpage, current readings at the Arduserver on sensors and internal counters and digital I/O pins. Full sourcecode available (free). Search on Arduserver. They've worked reliably on the whole. One needs rebooting from time to time, but that's probably a flaw in my software. The Arduserver-served page includes machine-friendly versions of the data returned. I offer (free, incl sourcecode) Windows software to read an Arduserver, log a history of readings seen, and plot realtime graphs of the values observed. In one version there's a low temperature alarm. If the temperature in House A is lower than it is meant to be (i.e. heating has failed, and pipes may freeze), an alarm starts beeping at House B. I'm not sure I've published that, but you could write your own easily enough... if you had an Arduserver at House A!

This was exactly the module that I was looking for to work for my project. It is easy to program, great for prototyping and performs the functions that I need just like an Arduino would. The main feature of this that I like best is the WIFI which is what I need for my project to work well.

This is well-supported by MicroPython as well as Arduino. The combination of USB-selectable bootload mode and easy WiFi setup makes it straightforward to get a useful system image onto the board and from there arrive at a wireless development environment.

I have several of these units doing IoT stuff around the house. Overkill as I never use the LiPo facility but they are very reliable and well supported like all Adafruit products.
