Adafruit Assembled Feather HUZZAH w/ ESP8266 WiFi With Stacking Headers

The Adafruit Feather HUZZAH ESP8266 is a compact, lightweight development board that seamlessly integrates the ESP8266 WiFi microcontroller, offering an ideal platform for Internet of Things projects.

Equipped with an 80 MHz ESP8266 core and 3.3V logic, this development board supports Arduino IDE programming, simplifying project setup and enhancing development speed. Its built-in USB-Serial converter enables rapid code uploading at rates up to 921600 baud, featuring auto-reset for efficient programming.

Designed for portability, it includes a connector for 3.7V Lithium polymer batteries with integrated charging capabilities, allowing for USB or battery power options. With automatic power switching, you can transition between USB and battery seamlessly.

Compact dimensions of 2.0" x 0.9" x 0.28" and a weight of just 9.7 grams make it perfect for portable projects. It features 9 GPIO pins for I2C and SPI, a 1V max analog input, and two onboard LEDs for bootloader debugging and general purpose blinking.

Backed by a sturdy 3.3V regulator supporting a 500mA peak current output, it comes fully assembled and tested, ready to utilize the Arduino IDE or NodeMCU Lua right out of the box.
