It means that there’s some sort of hardware problem. When you open your Arduino IDE Serial monitor and the error message “Brownout detector was triggered” is constantly being printed over and over again. Brownout detector or Guru meditation error If that is the case, you may get a new OV2640 camera probe. If you get this error, it might also mean that your camera or the camera ribbon is broken. Some readers also reported this problem was solved by replacing their actual FTDI programmer with this one. If you’re powering your ESP32 through a USB port on your computer, it might not be supplying enough power. So, you need to change the pin definition in the code accordingly to the board pinout. You might need to check each gpio declaration with your board pinout.įor example, M5Stack board without PSRAM has a different pin assignment than the M5STACK with PSRAM (defined on the code by default). There are many esp32-cam boards being released (“fake boards”) that the wiring between the ESP32 and the OV camera might be different, so selecting the camera module, might not be enough. Otherwise, it will fail the pin assignment and the camera will fail to init. In this example, we’re using the CAMERA_MODEL_AI_THINKER, so it’s the one that is enabled. You just need to uncomment the right camera module and comment all the others: //#define CAMERA_MODEL_WROVER_KIT Make sure you select the right camera module in your projects. When you get this error, it might also mean that you didn’t select the right board in the define section or the pin definition is wrong for your board. The camera has a tiny connector and you must ensure it’s connected in the the right away and with a secure fit, otherwise it will fail to establish a connection. Sometimes, unplugging and plugging the FTDI programmer multiple times or restart the board multiple times, might solve the issue. If you get this exact error, it means that your camera OVX is not connected properly to your ESP32 board or you have the wrong pin assignment in the code. Measure the output voltage of your FTDI programmer (VCC and GND) using a Multimeter to ensure it’s providing 5V to your ESP32-CAM. Some of our readers reported that they could only upload code when the ESP32 was powered with 5V. One of our readers reported the following: “ found out that you can program the board with a USB-to-TTL module model CP2102 and that the CH340 model does NOT work“. Also, check that you have the FTDI programmer jumper cap set to 5V. You should also press the on-board Reset button to restart your ESP32 in flashing mode. Important: if you can’t upload the code, double-check that GPIO 0 is connected to GND and that you selected the right settings in the Tools menu.
