Does the PD board Output 12v Stable?

We are aware of this; we will wire the serial port to the gpio of a digital sidecar.

If it can't do what you're trying to do with an off-cRIO processor, I'd be surprised.

Our robot design has forced us to become something of a sniper - we should have the accuracy, and want additional speed in processing images. We may use a second camera to help with targeting.
The fact tha the old processor was 1/100th of the current one doesn't mean the new one is blazing fast, it means the old one was very slow.
I don't view ~450 mhz as very fast, particularly when we can only get image processing (at the lowest possible resolution) to run at about 20 fps, with nearly no other operations running simultaneously.

Do you mean 20 amps?
Watts = Amps x Voltage
20 = Amps x 12
Amps = 20/12 = 1.67

I'm pretty certain that the motors draw more than that.
