If I may add something, I know a big rookie mistake (we all make) is drill and file other pieces of the robot around the electrical board. These resulting bits and filings of metal and plastics can float around and find their way into the small crevices of the wiring inputs for all of the electronics
I have seen (and smelled
) more electronics burned at Regional and local offseason competitions than I wish to elaborate about. If you are a team making last minute changes right ontop of your final robot (we all do that at one point or another) without putting some kind of bag or block over the electronics package (something I highly encourage), expect something like your cRIO, PDB, Victors, and Jags to F-R-Y: Fry!
Best of luck this season!
