Electronics used to be all 5v. You can't do that anymore. It's all 3.3v. Because of woke.

@foone do you know why 5v got chosen in the first place?

@robryk isn't it something to do with CMOS ICs?

@foone it's older: 7400s (which were originally TTL) require 5V, while 4000s have a much wider supply voltage range (apparently 3-15V).
