Can anybody suggest a good optocoupler for use between a planetcnc usb control board and a DRV8825 step motor driver? I read somewhere where somebody said that optocoupler selection is important so that it does not disrupt the step signal to the driver and since I am very new to building a CNC machine, I was wondering if anybody knows of a good optocoupler breakout board or optocoupler that I can put between my control board and drivers.
Thank you
