I'm considering using the KFlop with servo motors, probably DC brushed. I'd like a drive that works well with the KFlop, but with more power than the SnapAmp. The type of motors I'm considering have peak current ratings 2X to 3X that of the SnapAmp. It seems a shame to be limited by the crrent capabilites of the SnapAmp.

However, the motor drives I find with larger current ratngs all expect to close the PID feedback loop themselves. Instead, I'd rather close the loop in the KFlop.

So what I think I want is a rather dumb power amp, with no extra features (like encoder feed back, PID, etc.). Something like a rather bare H-bridge, with perhaps some basic over-current protection and recirculation, but not much more. The amp/drive needs to respond to the KFlop's step/direction commands, of course.

Any suggestions?

Part 2: Given my stated problem above, could the KFlop directly generate the PWMs required to drive the individual transistors of a 'dumb' H-bridge?

Thanks!!
