Features:
Built around ESP32-WROOM-32, this minimum system development board achieves optimal performance with its rich peripheral set, Wi-Fi and Bluetooth connectivity offered by our flagship SoC, ESP32. The limit is your imagination!
Rapid Prototyping
Get right into application design and development without worrying about RF performance and antenna design. ESP32-DevKitC has your basic system-requirements already covered. Just plug in the USB cable and you’re good to go!
Flexible and Feature-Rich
ESP32-DevKitC contains the entire basic support circuitry for ESP32-WROOM-32, including a USB-UART bridge, reset- and boot-mode buttons, an LDO regulator and a micro-USB connector. Every important GPIO is available to the developer.
Breadboard-Friendly
The ESP32-DevKitC pinout is optimized to enable prototyping on a breadboard. The on-board LDO output is led out for powering up additional off-board electronics. Peripheral outputs are grouped together for hassle-free prototyping.

NB: Untuk 32U wajib pake antena Eksternal, karena kalau tanpa antena sinyal WiFi yang terdeteksi cuma sedikit atau malah tidak dapat sama sekali
