At the Feather HUZZAH's heart is an ESP8266 WiFi microcontroller clocked at 80 MHz and at 3.3V logic. This

microcontroller contains a Tensilica chip core as well as a full WiFi stack. You can progam the microcontroller using the

Arduino IDE for an easy-to-run Internet of Things core. We wired up a USB-Serial chip that can upload code at a

blistering 921600 baud for fast development time. It also has auto-reset so no noodling with pins and reset button

pressings.
