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.
