Would it be legal/possible?
I was wondering if it was possible to take 12V RGB LED Strip and plug it directly into the PD board to light up the robot. The RGB Strip has a 12V connection but I cant seem to find the ground. Is this legal / possible?

You should be fine as long as they are simply dumb (ie. not digitally controlled) strips. Keep in mind that they will dim when your battery voltage drops.
I don't really understand what you mean by saying you can't find the ground. The LED strip should have two wires, one black and one red. They should go into the correspondingly colored ports on the PDP. A part number/link would be helpful. |

If you just want it to show a single color, you should just be able to plug the +12v wire into the positive on the PDP, and the R, G, and/or B wires (in any combination) into the negative on the PDP.
It would want more control, I would recommend using an Arduino and some transistors to control the channels with PWM. You could also try using the PWM outputs on the roboRIO, but their low frequency might cause come flickering. This Adafruit tutorial should help with wiring the transistors to an Arduino (or to the roboRIO PWM outputs). |

There are 3 ground wires, one for each of the different LEDs in each light. IE one for Red, one for Green and one for Blue. Depending on which one(s) you ground and how frequently they are cycled on and off you'll get the different colors.
How it all works is explained in the first paragraph of the description. |

So it would be legal to wire it directly to the PD Board

Just a reminder, VRM's 2A rating is peak, nominal is 1.5A.

Re: Would it be legal/possible?
What happens if you exceed the 2amp out put on the VRM or can you?

In Beta I think I remember the result of overloading it for at least one team being a cooked VRM. |
