Adafruit HUZZAH32 overview
The Adafruit HUZZAH32 is an ESP32-based Feather, made with the official WROOM32 module. Every design feature appealing about Feathers: built in USB-to-Serial converter, automatic bootloader reset, Lithium Ion/Polymer charger, and just about all of the GPIOs are featured in the Adafruit HUZZAH32 - ESP32 feather development board.
The WROOM32 module included in this Feather Dev Board contains a Dual-Core Wi-Fi Dual-Mode BLUETOOTH® ESP32 chip, 4MB of SPI Flash, and a tuned antenna. In addition to Wi-Fi and Bluetooth Classic/LE support, the ESP32 offers more GPIO, plenty of analog inputs, two analog outputs, and multiple extra peripherals (spare UART).
