Iwas successfully able to connect my esp32 cam to ftdi programmer and I uploaded the camera webserver sketch successfully, when I open serial monitor to read the ip address for the camera, it constantly displays brownout detector was triggered and the esp32 cam resets, do you know why this would be happening?

Try switching to 5V instead of using 3.3V

I connected 5v to the esp board 5v pin and the results are the same with either 3.3v on 3.3v pin or 5v.  I tried connecting a external 5v souce to the 5v pin and used the the ftdi to program the board the results are still the same. The board responds to programming with all 3 of these configurations, but I still get the same error.

Can you double-check your camera connection? It looks like a connection issue between your camera and ESP32.

I think it either means:

  • Not enough power through USB source: Some ESP32-CAM boards required 5V power supply to work properly. We’ve tested all our examples with 3.3V and they worked fine. However, some of our readers reported that this issue was fixed when they power the ESP32-CAM with 5V.
  • The camera/connector is broken or not properly connected: If you get this error, it might also mean that your camera or the camera ribbon is broken. If that is the case, you may get a new OV2640 camera probe.
