Running more than 1 oDrive. Solutions?

Hi there!

I would like to run 2 oDrives with a teensy and am stuck reading about problems with ground loops. Any tutorial out there about this subject?

The information we have here is definitely not enough. For example I have no clue what to choose as isolator and where to buy it from. Or how the actual schematic would look like.

Any guidance it truly appreciated!
