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.
Honestly a little moisture isn’t going to short it unless you’re setting it in a literal puddle. I really wouldn’t worry about it being exposed, it’s not really a problem. Something like electrical tape would protect you if you put something metal against it, but an amount of water that would cause problems isn’t going to be stopped by some tape.
The reset/boot part of the SEA-PICRO uses 4 MOSFETs, so that makes it a little more sensitive to ESD and short circuits. Covering it with something would be good since keyboards can move around more, are subject to more abuse and people who have hobbies like this are more likely to have bits of metal (or screws) on their desk.
I would generally agree with you about the exposed pins not being and issue, but for this application, a little more protection will go a long way.
