I recently purchased a klor from beekeeb, ready soldered :) excellent soldering job; in any case. I didn’t realise that the mcu would be exposed. So i was wondering if I should be worried. I don’t want to stick black electrical tape over it because it will get sticky. Wondering what i could do. Worried i move the keyboard one day with moisture on my fingers and then i get a short, which will be a sad day. Thanks.
Asked a similar question years ago and some suggested fingernail polish. Not sure how easy it would be to get off in case you must. Never tried it myself.
Plastidip should do the job elegantly if you manage to apply it cleanly enough.
