Some ports can be controlled with an output:
- Bus = WIO ID
All other settings are default.

Arduino IDE
The ESP32-CAM board does not feature an USB connector, so a separate USB programmer board is needed.
There are many clones of this ESP32-CAM board. Important is documentation on how to connect and program the board, and which camera is mounted.
This test board must be programmed in the Arduino IDE with the ESP32 Wrover Module board type:
The mounted camera must be selected in CAM.h.
For this test board select:
#define CAMERA_MODEL_AI_THINKER
Pinout
- GPIO04 = Flash LED
- GPIO33 = on board LED
- GPIO16 = Seems to be used by the camera. (I2S)
