Adafruit HUZZAH32, ESP32 Feather Board

Adafruit Feather HUZZAH32 ESP32 - the "all-in-one" developer board based on the WROOM32 with dual-core ESP32 chip with integrated WLAN and BLE, USB port and charging circuit for 3.7 V LiPo batteries.

The Adafruit Feather HUZZAH32 board has an Espressif ESP32 microcontroller with integrated WLAN and Bluetooth Classic and Bluetooth Low Energy (BLE) support - ideal for IoT applications! The processor is operated with 3.3 V and clocked at 240 MHz. The chip has 4 KB of flash memory and a complete WLAN stack. The programming is done, for example, via the Arduino IDE.

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 HUZZAH32 board automatically switches from battery to USB operation when the board is connected via USB.

The ESP32 microcontroller is the perfect upgrade to the ESP3266: It has significantly more inputs and outputs, more analog inputs, two analog outputs, additional peripherals, such as an additional UART and a dual-core processor with a much higher clock rate. With the second core, your own program no longer has to share the computing power with the integrated WiFi manager.

Please note that the Feather HUZZAH32 ESP32 Board is currently aimed at developers or Makers who already have experience with microcontroller programming. Not every periphery is fully documented and there may still be errors. I2C, SPI and queries of analog inputs are already working and further features are under development and will follow.
