CNC Controller Stepper motor driver DM420A 1.7A 12-36VDC 128Micostep for NEMA17

Sep 24, 2019

It´s good but beware of low input impedances.

It's a good product, the stepper motors run very smoothly. But the pulse input impedance is too low for the ESS stepper PCB to drive it so I have inserted a "P" channel and an "N" channel mosfet in push-pull mode to drive the input. It works fine now.
