To flash, connect GPIO0 and GPIO2 to GND, remove the camera, power it with 3.3V, not 5V.
The board needs to be programmed with ESP-IDF as explained in details in Github, https://github.com/donny681/ESP32_CAMERA_QR
and there’s no Arduino IDE support.
So if you’r not comfortable with using Espressif development framework better skip this board.
The demo code takes a QR code, and outputs it as ASCII code in the serial console.
Mark HurleyIhad to power it with 5V to get the camera working properly. And this is compatible with Arduino IDE -- just be sure to add ESP setup beforehand.
