Adafruit HUZZAH32 – ESP32 Feather Board

Key Features:

• 240 MHz dual core Tensilica LX6 microcontroller with 600 DMIPS
• Integrated 520 KB SRAM
• Integrated 802.11b/g/n HT40 Wi-Fi transceiver, baseband, stack and LWIP
• Integrated dual mode Bluetooth (classic and BLE)
• 4 MByte flash include in the WROOM32 module

The HUZZAH32 is Adafruit's ESP32-based Feather, made with the official WROOM32 module. It's packed 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.

That module nestled in at the end of this Feather contains a dual-core ESP32 chip, 4 MB of SPI Flash, onboard 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.

Compared to the the ESP8266, the ESP32 has more GPIO, plenty of analog inputs, two analog outputs, multiple extra peripherals, two cores so you don't have to yield to the WiFi manager, and much higher-speed processor! We think we'll see more people move to this chip exclusively, as it is so full-featured. Not all of the peripherals are fully documented with example code though. Some bugs still being found and fixed. For that reason, we recommend this Feather for makers who have some experience with microcontroller programming.
