Powering a coprocessor

I recently bought a Odroid c1. It is supposed to take 5v at 2 amps. I checked the frc rules and it said the only device allowed to be powered by the 5v 2a rails on the vrm is the bridge. is there a way i can power this thing without breaking the rules? I was thinking about the 12v dc converter from last year but was wondering if there is any easier option like having two vrm instead of a pcm and using one of the 5v2a rails for the radio and one for my coprocessor, but according to the rules the only thing that can be connected is the radio power.

Re: Powering a coprocessor

You could use a different voltage regulator module connected to a standard 12V circuit on the PDB.

Re: Powering a coprocessor

From the specifications:
Quote:
This is for 5V power input, with an inner diameter of 0.8mm, and an outer diameter of 2.5mm. The ODROID-C1 consumes less than 0.5A in most cases, but it can climb to 2A if many passive USB peripherals are attached directly to the main board.
If you're not using any USB devices, you can probably get by with the 0.5A rail on the VRM. If you are using USB devices, plan accordingly.

Re: Powering a coprocessor

R32 requires the radio to be connected to a VRM, on the 5V 2A rail, and nothing else can be on that rail. It does not prohibit additional VRMs from being installed on your robot.

Re: Powering a coprocessor

Should I plug in last years voltage regulator into a 30 amp?

Re: Powering a coprocessor

Use the old power regulator off the 12v. It works. You will need the 2 amps. I have set up the Odroid u2 and u3 this way.
