Great stuff, really want to get my hands on the pixhawk 4, but trying to understand it as best as I can for my own project. If you don't mind two questions i got if you could help, if you know, am I right in saying the pixhawk supply's power to the GPS and receiver? (Not the USB or servo rail) Also when it comes to the servo rail, it says max input voltage is 36v. So am I right in saying I could potentially connect 3 12v car batteries up in parrell to make 36v...and then connect that directly to the servo rail with no problems?
