Stepper Motor Controller PWM Pulse Signal Generator Speed Regulator Board £6

[JohnHaine]

Well that is very confusing! Is it a variable frequency generator to drive a stepper motor (it says that a separate drive is needed) or a PWM controller? There's a meaty device with a heatsink but maybe that's just a regulator as it says that you can supply from 160 V.

Either, it depends on the jumper setting.
