I had to solder a wire to it, there isn’t a pin header on this edge. On my FTDI board this pad is located 4 holes up from the end on the long edge of the board. The correct solution is to give the the +5V it requires from the terminal pad labeled “5V” on the FTDI board. So the red wire in the hook-up diagram is incorrect. That regulator won’t work if you only give the board 3.3V to start with. 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.

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.')
