Arduino Nano Clones Not Working

[anon44338819]

Let me just say that when I refer to "it", I mean "all three" .

1. Does the L led blink (you don't mention it specifically)? If so, the power led might not be properly connected to the 5V but board is possibly OK.

No. All lights are off.

2. Visual inspection for bad or missing soldering. You can fix those if you have the skills but you might void the return policy.]

All soldering looks good.

3. Plug it in and check the 5V output? Make sure that both sides of the the cable are properly inserted. No 5V output could indicate a bad cable.

There is no 5V or 3V3 output, also with a different cable.

4. Disconnect the Nano from USB and apply 5V to the 5V pin (you can use the 5V output of e.g. your Uno).

On all 3, the power LED comes on, but when pressing RESET, the pin 13 LED does not flash.

Most Nano clones have the old bootloader as firmware.
You need to select "Old Bootloader" in the IDE menu.

They don't even turn on, so the IDE is useless.

Can you please post some images of the Nanos, both sides would be great?

Do you have a DMM?

Only an analog multimeter .

It's a long shot, but a common problem - did you try a different USB cable? Many the hour has been wasted fighting with devices downstream, when a defective cable was the root issue.

Yes, same thing happened
