I don't know much about steppers but I'd like to ask a question... if it were legal, how would it be wired to the roboRIO? What is its voltage and current specs?

One mystery I've been tracking deals with the loss of the Vex 393 being legal, and while I have yet to find the official answer why it was pulled... I'm guessing its electrical needs are not quite a good fit for the roboRIO. I'm still working out the amp draw from the roboRIO vs. the digital side car.

As I recall there were several rules about the wiring that prohibit any special wiring needs to manage the voltage... so for example if I wanted to use the 393 I could either provide a separate 7.2 power source, or wire my own voltage regulator. (these things would be discouraged). So I'm curious how good of a fit these stepper motors would be in terms of wiring.
