Pretty sure this board has some kind of ESD protection built in, it uses an ARM processor.

Did you use the very bottom thin insulation sheet? How quality is that cable you are using? The cable could possibly be the cause, if it's not grounded properly.

You could try reflashing the firmware (White caps LED: VIA version, VIAL Version, Red caps LED: VIA Version, VIAL Version) too, if the board is responding at all (which it seems it very well may be), this could recover it.

However, even with the money I spent on this board and others, I always buy at least 1 spare PCB.

There's numerous people reporting the same problem. Just by having an ARM CPU doesn't make it immune. You still have to provide ESD and surge protection circuitry on all data, power and ground nets of the PCB. It sounds like it was either designed incorrectly, or skipped all together.

Afaik, it was designed with it. There's MANY others that apparently don't have this issue, like myself. I have 2 PCBs from them. It's cold af where I am right now. Dry air, carpeted room. ESD heaven. No issues so far. I'm not saying ESD didn't kill theirs, but there's no widespread issue. Defective parts happen.

There's numerous people reporting the same problem with pretty much any other board...

While all your "keeb build stream gurus" still showing you to handle PCB's w/o any precautions... but of course whole community jumps onto maker...

Lol, no there aren’t. This is not normal. Nor is your white knighting a company making expensive defective keyboards.

They are - do some search .

Never said this is normal. Those incidents are surely not normal occurrence, but Jumping to conclusion without professional investigation just proves your ignorance. No pro will make such conclusion just because "numerous people" managed to damage their boards.

And this has nothing to do with the maker - the typical childish mantra of accusing me to somehow covering for the company just disqualifies you from further conversation.

Paragraph after paragraph of you defending a keyboard maker’s products dying from ESD by touching the keycaps is hilarious, please keep going!

Take a picture of the ESD protection ICs on the data lines going from the switch rows and columns to the MCU.

I think you put your comment in wrong thread.

Nope, it's the correct one. It was rhetorical and you totally didn't get it. ;)

Because it makes no sense not relevance whatsoever.

Thanks for the info and I will try that. I did use all the sheets and foam. The cable is an Anker cable.

Let me know if it works to resolve the issue or not. Based on your other comment, it sounds more like the firmware on it became corrupted instead of killing the board. Good chance a reflash can resolve at least the keys not working.

Just to follow up, I did reflash the board but didn't fix the problem. I e-mailed Graystudio and they are supposed to be sending me a new PCB.
