Resources about espressif's ESP32 soc

ESP32 is a tiny soc with 2.4G WiFi and Bluetooth 4.2 in one combo chip. With a few other compoments, users can use this chip to assamble electronics, like IOT module, camera video stream deliver, wearable devices and so on.

This Project collects resources about ESP32, to help users to make a better using of this interesting and powerful chip.
