본 제품은 ESP-WROOM-32 모듈이 탑재된 ESP32기반의 마이크로컨트롤러 보드입니다.
ESP32는 WiFi, 블루투스 클래식 및 BLE를 지원하는 모듈로 ESP8266의 업그레이드 버전입니다.
보드는 USB-Serial, 자동 부트로더 리셋, 리튬배터리 충전회로 등을 지원하며 모든 GPIO의 접근이 가능하게 디자인되었습니다.

Please note: The ESP32 is still targeted to developers. Not all of the 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.
