However we've successfully hacked them in the past to drive the MOSFET with PWM from an Arduino. If you don't need the full 50A, we have smaller motor drivers that are more Arduino-friendly.</p>

It shouldn't matter, as long as you send it the correct signals, right?</p>

It should be easy to program up your own PIC chip just the way you want it. The pots seem to simply provide setting inputs to the PIC chip.</p>

And the soft start feature is awesome!</p>

you always say we should let you know about our projects in emails and stuff... but you never say where!<br>
I have recently built a walking chair using this speed controller. and i just thought I'd let you know.<br>
