Pinout

FireBeetle Board - ESP32 is not only compatible with ESP32 Pinout, but also compatible with Arduino IDE PinMap. Users can directly use Dx(x=0,1,2,3...9) to control the corresponding GPIO port when programming on Arduino IDE.

DFR0478-Pinout

NOTE:

There is no electrical connection at NC port.
The output voltage of the pin VCC is equal to power source's voltage. (Output USB voltage when powered by USB, output battery voltage under 3.7V lipo battery input)
The VCC port usually is not used as the power supply port of the mainboard. If you have to use that port to power the mainboard, then the battery input pin should be left floating.
