Adafruit Feather HUZZAH with ESP8266 WiFi

9.500 KD


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!


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 interpreter). 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
