Feather of the Day: Adafruit Feather HUZZAH with ESP8266 #Adafruit #Feather #ESP8266

The Adafruit Feather ecosystem is so rich with hardware diversity, we wanted to share them, one each day. Today is the Adafruit Feather HUZZAH with ESP8266!

The Adafruit Feather HUZZAH ESP8266 is our take on an ‘all-in-one’ ESP8266 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!

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.

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 baud rate for speedy uploading
  • Auto-reset support for getting into bootloader 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
  • Reset button
