Our team just finished the FRC competition and I am trying to learn more about robots in general. I'm trying build a robot in a similar setting than the FRC competition. However the RobotRIO is out of my budget.
I'm currently set on buying a Raspberry PI 3B as main controller board as replacement for the robotRIO.
However, I do not quite understand how I'm going to power 12v motor. In our FRC build we had this power distribution panel, but I'm pretty sure I will fry my raspberry PI.
I believe I need some kind of power distribution board to have 5v and 2.5a for the Raspberry PI. And also 12v on some other pin. Does this exist or am I looking for something that do not exist.
My build would be powered by a 12v battery like these Interstate Batteries (am-3062).
