Adafruit Feather HUZZAH with ESP8266 WiFi

Adafruit Feather HUZZAH ESP8266 - the "all-in-one" developer board with ESP8266 WLAN, USB port and charging circuit for 3.7 V LiPo batteries.

The Adafruit Feather HUZZAH board has an Espressif ESP8266 WiFi microcontroller, which is operated with 3.3 V and clocked with 80 MHz. The chip has 4 KB of flash memory and a complete WLAN stack. The programming is done, for example, via the Arduino IDE. A SiLabs CP2104 is used as the USB serial chip, which supports a baud rate of up to 921600.

Ideal for mobile applications! The board has a connection for 3.7 V LiPo batteries and a charging circuit. The board can be operated and the battery can be charged via the microUSB port. The Feather HUZZAH board automatically switches from battery to USB operation when the board is connected via USB.

Product features:

• Dimensions: 51 mm x 23 mm x 8 mm (without pin headers)
• As light as a (big?) Feather - 9.7 g
• ESP8266 @ 80MHz at 3.3V
• 4 MB flash memory (32 Mbit)
• Built in WiFi 802.11 b / g / n
• 3.3 V voltage regulator with 500 mA peak current
• CP2104 USB controller for fast uploads (baud rate up to 921600)
• 9 x GPIO pins, can also be used as I2C and SPI
• 1 x analog input (up to 1.0 V max.)
• Integrated 100 mA LiPo charger with LED charge status display
• Red LED on pin 0
• Green LED on pin 2

Each module is delivered assembled and tested. You can solder on the enclosed pin headers if necessary. The firmware is already NodeMCU incl. Lua interpreter on the ESP8266. So you can start directly with Lua programs via the serial interface or you can use the Arduino IDE for programming.
