I think that I have a bad board. I have 2 identical boards from the same merchant and one connects ok and the other doesn't.
I wonder how that happened. Would an excess voltage fry the uart chip ?
The chip is a Silicon Labs CP2102.
Well nuts, I have a 2nd NodeMCU with the same chip and it also cant connect.
Is there a definitive way to verify this ? Maybe I got a sometimes faulty cable ?

nope, its not the cable. They are both bad. Grrrrrrr >:(
Since you haven't said what to, or how you connected the board, we would only be guessing.
The chip is a Silicon Labs CP2102.
They don't have the DTR signal required for an auto reset so if you want to load code you have to do that trick of holding the reset button and releasing it about one second after it prints "uploading".
Been many years since I used that technique.

Well, the board is plugged into my PCs USB port, I fire up the Arduino IDE and, under tools, the port is greyed out.
SteveMann, not being snarky but what else could I have done that would show the port as grey.
I thought that it was obvious, and I am eager to learn.
Do you have the Windows USB driver for the Silicon Labs chips installed?
