Great! Sounds good. I also have one more question before im off to my planning, when I make my custom regualtors, can I use a 90k ohm resistor on lets say the 3.3v voltage which only needs 1.89k ohm? So can I just buy like 10 90k ohm and use 4 of them with my regulators?You don't have to sand a bunch of the board away, just make sure there are no shorts on the sides.
