Powering two compressors with one PCM

And don't try to put it in reverse! IIRC, we connected the black lead of our compressor directly back to the Power distribution board (through a splice), and just put the red lead to a spike output to ensure that we didn't apply reverse voltage. (I never found a rule AGAINST it.) While you can't use the other output on an FRC-legal robot (per 2016 R53, second sentence), for other projects, you can use that side to control something else, like a string of LEDs or other low-current-draw custom circuit.
