Jaguars failing

[Chris_Elston]

Thanks for this report.

Looks like ours is a U6/U7 failure.

Team 1279 worked on the Black Jag Beta program and we did manage to blow up two with static discharge, one by accident, and one on purpose (under TIs direction). Last years robots were very static prone, and the encoder and potentiometer inputs are fairly exposed. I would recommend covering the inputs with empty connectors when not using them to prevent that type of failure.

I would note that we also blew up our Kwik Byte driver station's ethernet connectors when running tethered at a fundraiser, so the Jaguars are not the only static sensitive devices. Use due care with all your sensors, etc..

TI was very good to work with about the failures, and they seem committed to improving their product. I would say that any team who has a failure should contact TI, document the conditions, and return the blown part. The Jags have many cool features and I would very much like to see them become a reliable component.

Oh you silly Northerners! There is a simple fix to your whole static discharge problem...MOVE TO FLORIDA! Sure, the education system isn't as good and there's a constant threat of hurricanes, but it's not very often my car shocks me!
