So found some tiny rumble motors at microcenter that run off of 3v. They are the perfect size for a portable....like <10mm in diameter and 4mm thick. The problem is I don't know if putting 3.3v with a resister to bring it down to 3v, if it's necessary, instead of 5v on the controller line would work. Anyone have any experiences putting lower voltage through the 5v line on a GC controller?
