Hi, i have putting together a cnc shield and was planning to have some sort of isolation between the Step/Dir signals and the arduino. I am a little out of my depth here but here goes. I think i need some sort of digital optoisolation as i need to be careful of jitter due to software which means …

This is the drive im going to be using but i would like the board to be able to support different drives.
I would also like to add a bit of future proofing and make it suitable for the due.
