Discuss mitigation practices for DO circuits #131

Brainstorm if there's any hardware implementation or design modification on our DO PCB to protect our DO circuit
What can we add to our testing workflow to mitigate this issue?
Determine why our DO circuit is continuing to get damaged?

Note 12/1 - Found that a pin on the EZO isolator board is left floating (OFF pin). Data sheet says that it can be left floating, but we should tie it to VCC in our PCB. Will need to do further testing to see if this will protect our DO Circuit
