NC Pins

V3 Chips

  • Pins GPIO6 to GPIO11 on the ESP32-D0WD-V3/ESP32-D0WDR2-V3 chip are connected to the SPI flash integrated on the module and are not led out.

V2 Chips

  • Pins SCK/CLK, SDO/SD0, SDI/SD1, SHD/SD2, SWP/SD3, and SCS/CMD, i.e. GPIO6 to GPIO11 are used to connect to the module integrated SPI flash, not recommended for other functions.
