it's the for Feather you have been waiting for, and now with stacking headers! The HUZZAH32 is our ESP32-based Feather, made with the official WROOM32 module. 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. We have other boards in the Feather family, check'em out here. That module nestled at the end of this module 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 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. The ESP32 is a perfect upgrade from the popular ESP8266. In comparison, the ESP32 has way more GPIO, plenty of analog inputs, two analog outputs, multiple extra peripherals (like a spare UART), two cores so you don't have to yield to the WiFi manager, and much higher-speed processor, etc. etc!
