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.
Use Silicone Conformal Coating. It’s a clear silicone liquid you can apply over the whole circuit board and it makes it waterproof while leaving the PCB visible. You can even do repairs on it with a solder iron (the coating melts under the iron). We use that for FPV drones.
