Adafruit HUZZAH32 ESP32 WiFi® Development Feather Boards

Adafruit HUZZAH32 ESP32 WiFi® Development Feather Boards are manufactured using the official WROOM32 module. These feather boards feature built-in USB-to-Serial converter, automatic bootloader reset, lithium ion/polymer charger, and General Purpose IOs (GPIOs) for use with any of the Feather Wings. There are two versions of this HUZZAH32 WiFi Development Feather board. The one (with product id - 3619) comes with stacking headers, whereas the other (with product id - 3591) comes with plain 0.1" headers (pre-soldered).

The WROOM32 module included in this Feather contains Dual-Core Wi-Fi® Dual-Mode Bluetooth® ESP32 chip, 4MB of SPI Flash, and a tuned antenna.
