Question. I ordered some small rectangular SMD LED's and am planning on soldering them to the bottom of the pcb of the KC60 using this acrylic case. Can I keep the key switch LED's in place and just solder my smd's onto the same spot as the key switch LED or will that draw too much and would it cause the key switch LED to be dimmer than the surrounding key switch LED's? I don't plan on putting a smd led to every key switch, just the outer perimeter switches. Also, depending on the color of my smd led, would I also need resistors of some sort? Sorry so many questions. =) Thanks in advance.

You should be able to do it as long as the underside LEDs are in parallel. Looks like the ones you ordered are 3.0V and 20mA forward (assuming input is 5V via USB) - so you need 100 ohm resistors for each one. Maybe don't put too many - 20 of those LEDs draw nearly 0.5A

Thank you very much. I'll have to look up how and on which leg to solder resistors on. Entering unknown territory. Just don't want to hurt me shiny new kb.
