The USB port can be used as the power supply for the circuit

Micro USB connector

board or the communication port for connecting the PC to the

ESP32 series module.

When the development board is powered on (USB or external 5

5V Power On LED

V), the indicator will light up. See schematics in related

documents for more information.

Most of the pins of the on-board module have been drawn to

I/O

the development board's row pins. Users can program ESP32 to

realize PWM, ADC, DAC, I2C, I2S, SPI and other functions.

Note: For specific function instructions, refer to the user manual of the ESP32 series corresponding module.

Note: 1.P: power supply; I: input; O: output;

2.Pins D0, D1, D2, D3, CMD, and CLK are used for internal communication between th

e ESP32 chip and the SPI flash and are centrally distributed on both sides of the developmen

t board near the USB port. In general, it is best if these pins are not connected, otherwise

they may affect the work of SPI flash/SPI RAM.

3. Pin GPIO16 and GPIO17 are only applicable to the onboard ESP32-WROOM series and

ESP32-SOLO-1 development board. Pin GPIO16 and GPIO17 of the onboard ESP32-WROVER series de

velopment board are reserved for internal use.
