In collaboration with Google and Mongoose OS, Adafruit's releasing an IoT Core Pack based around our Feather HUZZAH32! This kit includes a pre-soldered Adafruit Feather HUZZAH with ESP32 WiFi and some sensors and components to get you started on your IoT journey.
Feather is a development board from Adafruit that, like its namesake, is thin, light and lets you fly.  We designed Feather to be a new standard for portable microcontroller cores.
This starter kit contains the Adafruit HUZZAH32 – ESP32 Feather Board - our take on an 'all-in-one' ESP32 WiFi development board with built-in USB and battery charging. It's an ESP32 WiFi module with all the extras you need, ready to rock!
At the Feather HUZZAH's heart is an ESP32 WiFi microcontroller clocked at 240 MHz and at 3.3V logic. The ESP32 is a perfect upgrade from the ESP8266 that has been so popular. 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, much higher-speed processor, etc. etc! We think that as the ESP32 gets traction, we'll see more people move to this chip exclusively, as it is so full-featured.
