Isolating motor's power from controller/sensors power demands

Has anyone used an Optoisolator SparkFun Opto-isolator Breakout - BOB-09118 - SparkFun Electronics to separate the power demand of motors from the rest of their project’s components? Or does the oDrive board already do this?

I’ve seen a few robotic projects get into difficulties when the current draw from the motors caused fluctuation in the battery output. This isolator is intended to isolate the high current demands from the more sensitive components.

This should be used, yes. See the Ground Loops page. Ground Loops — ODrive Pro Documentation 0.6.1 documentation

ODrive Pro has isolated GPIO for this reason :slight_smile:
