This board is packed with features! Built in USB-to-Serial converter, automatic bootloader reset, Lithium Ion/Polymer charger, and lots of GPIOs. This board interfaces with the Crickit for Feathers.
This version of the ESP32 Feather comes with stacking headers already soldered in so its ready for instant gratification and Feather fun!
That module nestled at the end of this Feather 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 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.
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 a much higher-speed processor!
Please note: Not all peripherals are fully documented with example code, and there are some bugs still being found and fixed. We got all of our FeatherWings working under Arduino IDE, so you can expect things like I2C and SPI and analog reads to work. But other elements are still under development. For that reason, we recommend this Feather for makers who have some experience with microcontroller programming and not as a first dev board.
