Adafruit HUZZAH32 – ESP32 Feather Board

The HUZZAH32 is our ESP32-based Feather, made with the official WROOM32 module. HUZZAH32 comes with everything you love about Feathers: built in USB-to-Serial converter, automatic bootloader reset, Lithium Ion/Polymer charger, and just about all of the GPIOs brought out so you can use it with any of our Feather Wings.

This version of the ESP32 Feather comes with plain 0.1″ headers already soldered in so it’s ready for instant gratification and Feather fun!

That module nestled at the end of this Feather contains a dual-core ESP32 chip, 4 MB of SPI Flash, tuned antenna, and all the passives you need to take advantage of this powerful new processor. The ESP32 has both WiFi and Bluetooth Classic/LE support. That means it’s perfect for just about any wireless or Internet-connected project.
