but when I try to use hobbyist building blocks they don't work like I can't afford an arduino nano clone sucking down 15 mA in this circuit because they crammed a bunch of extra shit on the board and didn't care about power use. if I just use a PIC16 instead and build the board myself everything in this part of the circuit will draw less than 2 mA, which is fine RT: https://poa.st/objects/0ce3686b-984e-40f4-a785-a50858f98a6b
