Any solution available for for ESP32-cam 'Brownout detector was triggered' error?
Solution 1
Brownout detection is a hardware feature that shuts down the processor if the system voltage is below a threshold, also known as the "brownout voltage". This is to preserve memory contents and avoid corruption.
You are getting this message because your board is not correctly powered. The underlying reason could be one of many things:
- The USB cable is of poor quality, or too long.
- Your computer's USB port cannot supply enough power to the board.
- The ESP32Cam is defective
- Other components in your circuit are not correctly wired up, affecting the power supply.
I would try to power the ESP32Cam with another USB cable, a different computer, or an external 5V power supply. If all of that doesn't help, it could be that your board is broken.
Solution 2
I had this issue as well. I solved it by taking the following steps:
-
I originally had the ESP32-CAM powered off the 3.3V supply from my FTDI, but I then found it works better when supplied by 5V.
-
I had to jumper together the two pins marked in magenta to program the ESP32-CAM and then remove the jumper when I wanted the board to actually run:
- I had to select the "AI Thinker ESP32-CAM" in the Board Manager:
Solution 3
i had terrible brownout issues. struggled for days - tried everything on the forums.
Solution - just connect the desktop power to the esp32-cam and all my troubles disapeared.
seems the esp32-cam runs so close to the 5v power limit, that 5v from a desktop power supply is required when connected to the computer's usb port. not quite enough power and that makes all the difference.

I had an ESP32cam working for a few days then started getting that message at boot up. Reloaded the program and still no camera.disappointed

e-lab innovations over 4 yearsBut I am using power source from 12v 2A and used a 5v regulator (on the L298 motor driver board)
-
mikevanis over 3 yearsWhat kind of regulator are you using? Just because your power supply can give out 12V / 2A doesn't mean that your regulator is rated for that much. Also, does your regulator have decoupling capacitors on the input and output?

user8675309 over 2 yearsI had this issue while flashing a new board. I changed from a random cable connected to a usb hub to a different random cable connected directly to my PC's usb port and it resolved my problem.
