The development board uses the ESP32-WROVER module, which can omit the external PSRAM and reduce the difficulty of wiring. Compared with the official module, it is easier to download and burn. Most of the pins are compatible.
This development board has overturned but not completely. You can refer to the schematic diagram and use the PCB with caution.
Problem: When using the OV2640 camera for network projection, the image is accompanied by stripe noise. The problem is currently unknown.
SD read and write function has not been tested yet
