Just recently read the write up on ground loops and we have plenty of them
Specifically, we have several arduinos connected to odrives uart pins tx/rx/gnd. Assuming the ground is necessary we will need to decouple these lines.
Looking for an off the shelf isolator and found this one from Sparkfun but only operates at 9600bps https://www.sparkfun.com/products/9118
Is there a way to turn down the UART baud rate on the ODrive to 9600? I have been looking through the firmware and I can’t find an easy way to do that.
Are there any recommended GPIO/UART isolators to use available on breakout boards?
