Adafruit HUZZAH32 Feather Board | DigiKey Daily

Adafruit's HUZZAH32 is the ESP32-chip-based feather, which is a perfect upgrade from the very popular ESP8266 chip. When comparing these two ICs, the fully-featured ESP32 has many more GPIO, numerous analog inputs, two analog outputs, multiple extra peripherals, and dual cores. This dev board includes some of the favorite feather goodies, including a built-in USB-to-serial converter, automatic bootloader reset, and a lithium ion battery charger. Targeted to developers and equipped with both WiFi and Bluetooth transceivers, along with an on-board tuned PCB antenna, this ESP32-based feather is perfect for just about any wireless or internet-connected project. And because this platform is part of Adafruit's feather eco-system, its compatible with over fifty accessory wings.
