Re: Spike Control Line Signals

Thanks,
They are 5V signal level pins, they draw less than 10mA each. When I was hooking up the controls for the BattleCry6 Jeopardy game, I had trouble getting the blue ones to work off of a vex controller, although the red ones worked fine. I ended up using a vex pneumatics transistor driver to run a blue one, because we had an extra laying around and it was exactly what I needed (instead of spending the time to build it). I believe the PIC chips can sink 5mA or so of current, so apparently the blue ones are more than that. According to the post on IFI's website, you can run them off a mini-rc, which should be the same config as a vex controller. Who knows.

Edit:
Accoriding to the FAQ on IFI's site, the full size RC can supply 7mA on each digital out pin, not sure if the Vex controller is different.
