Robot Power Adapter
/One of our students showed me a useful gadget today. You can plug a 12 supply into it and get out 5v, 3.3v and the 12v going in. The two onboard regulators aren’t good for particularly high currents at around 800ma each, but this is a terribly useful controller if you are building a robot and want 12 for the motors and then the other voltages for your onboard devices.
