Hi guys, making a PCB for my Sharp PA1000H and want to keep the capslock LED. Anyone know how to power it/what voltage it is? How should I connect it to a Pro Micro (running QMK)? Thanks!

Normally is 2V 10mA. You can start at 1.5V 10mA and see if the brightness is OK for you. For 5V a resistor of 330 ohm can be a good start.

Alright, thank you.

So I am now ordering parts that I need, I will get a 330ohm resistor but should I just get some other ones of similar values to try them all out? Again, this is coming straight from the 5v Pro Micro so I am assuming 5v.
