Reply to comment by rcr432p in Space65 R3 - already dead from ESD! :( by aleksyandr

As far as I know only option is to replace PCB.

Sorry, what I meant to say is that the shocking part happened to me, but didn't kill my PCB. Any precautions I can take to avoid this outcome?

You can put a layer of something underneath on the bottom case under the pcb to stop the pcb from touching the metal

This is pretty irrelevant to this topic. You are talking about preventing unintentional shorting of the PCB in badly designed board - nothing to do with ESD risk.

….How else do you think they shocked the pcb in the first place? They touched the metal case, which discharged to the pcb. The only way that could have happened was the pcb was touching the case.

Sorry dude, I have no time to teach you basics of electronics but:

Correctly designed keyboard (and frankly any other device in metal case) will have it's PCB ground line firmly connected to the case for multiple reasons (ESD included).

Of course some customs have a flaw when other contacts of the PCB may touch the case and this needs to be prevented but not because of ESD risk but simply just to avoid shorting circuits.

... so... basically what the person above said is one of the many to discharge the electricity first?

I'm not sure what you are trying to say and who you mean by "person above" but if you wish to take extra precautions just touch PC case (assuming it is properly grounded) or elsewhere.

Oh, got it. I know that a humidifier inside can help reduce static charge build up. I don't know if some keyboards are more prone to it than others, or if there is something you could do inside to help protect it. I know some PCBs including the one for the Space65 are supposed to have ESD protection. I was using a V2 Odin prior to this one and never had the shock problem.

You can touch a heating radiator or water pipe to discharge yourself before you sit at the desk.

Have you tried reflashing the pcb in case your firmware was corrupted?

No, didn’t think to do that, but not sure how with this board.

I saw some talk on the discord that a major ESD will probably kill the LEDs but the rest of the board should come back by flashing firmware again.

What you can do is download qmk toolbox, and grab the binaries/hex files from the graystudio space65 r3 discord channel. They have instructions there for flashing. If you've never done this before look it up on youtube or feel free to DM me and I'll give you a hand.

Thanks for the link and direction. I was able to flash the firmware but unfortunately it did not work to fix the LEDs or the column that is out. :(

Oof, sorry to hear that. I hope they'll send you another board. Wish they'd keep a store open and put their stuff up for sale instead of group buys
