Adafruit HUZZAH32 ESP32 Wi-Fi® Feather Board

Adafruit HUZZAH32 ESP32 Wi-Fi® Feather Board, based on the Espressif Systems WROOM32 MCU Module, adds wireless connectivity to any Feather-based project. The HUZZAH32 ESP32 Feather Board also features a built-in USB-to-Serial converter, an automatic bootloader reset, a lithium ion/polymer charger, and General Purpose IOs (GPIOs) for use with any of the Feather Wings. 

The WROOM32 module included in this Feather 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).

The Adafruit HUZZAH32 ESP32 Wi-Fi Feather Board is offered in three variants. The 3591 features standard 0.1" headers. The 3619 features stacking headers. The 3405 comes with loose headers, so soldering is required.
