The takes the 5V input and regulates it down to 3.3V for the. The problem is that the needs 5V but the can only handle 3.3V. The FTDI jumper must be set to 3.3V.īUT with this 3.3V jumper set correctly, the VCC output voltage is too low to power up the. If you do, current will flow through the built-in protection diodes into the 3.3V bus, and this can damage the ESP32. The only runs at 3.3V and so you should never drive its input pins higher than that. Other errorsįor a more extensive list of the most common problems with the ESP32-CAM and how to fix them, read our ESP32-CAM Troubleshooting Guide.Įduardo you are correct, the jumper should be set to 3.3V. ![]() ![]() ![]() It might also mean that the ESP32-CAM is not establishing a serial connection with your computer or it is not properly connected to the USB connector. In your Arduino IDE, go to Tools > Port and select the COM port the ESP32 is connected to. It means that you haven’t selected the COM port in the Tools menu. The selected serial port Failed to execute script esptoolĭoes not exist or your board is not connected If you get the following error or similar: : could not open port 'COM8': WindowsError(2, 'The system cannot find the file specified.') Some readers were using 3.3V and reported that when powering the ESP32-CAM with 5V, the issue was fixed.īoard at COMX is not available – COM Port not selected.Use a different computer USB port or use a USB hub with an external power supply.Try a different shorter USB cable (with data wires).Or not enough power provided by the computer USB port.Board with some defect (bad solder joints).It’s often related to one of the following issues: 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 This error means that the ESP32-CAM is not in flashing mode or it is not connected properly to the FTDI programmer. ![]()
