We are debugging our AR4 robot. One thing we had wrong initially was the RJ-45 keystone jacks were swapped for 1 and 3. We mistakenly swapped the cables designated Top and Bottom in the manual. We have since corrected that and while the robot works we are now finding other issues.
Can swapping cables 1 and 3 have a destructive effect on the Teensy itself? Is there a way to test the integrity of the Teensy as we've checked most other components. We want to rule out the Teensy as a problem.
