My ESP32 Devkit V1 board is not detected by computer through USB, the LED Power is turn off. The led will turn on when i press "EN" button and off when i dont press it.

However,also the LED power is ON when i give 3v3 external powersupply with connected to 3v3 pin then i still can uploading program through USB. I have uploading blink program and running fine.

What just did i do before this problem come? I was uploading with Arduino IDE with wrong board in arduino board manager. I didnt focus, it was MH ET ESP32 DEVKIT while i should have chose DOIT ESP32 DEVKIT V1 in board manager.

Even thought i was wrong board, the program still successfully uploaded with both of board option (wrong board and true board) in board manager.

I dont understand how to troubleshoot this, im not sure the USB is problem.

1 Answer 1



I was checking it with volt meter, the VIN PIN was about half of VCC while it should be near VCC of USB power supply. So i just solder a point from board circuit which showed 5v in voltmeter then connect it (solder) to the VIN.

Then they are work fine.
