Re: Case for 971 Spartan Board?

Sam,

If you have dead boards, please send them back to us to take a look at.

We had a local business solder the black headers this year locally, so the boards should be quite a bit better. All the white headers/SMD components are done at the factory level.

We've had a few pins get bent on our offseason bot due to stuff falling on it and just made a plastic cover that goes over it. Also our roborio for our offseason bot is simply just gross, its covered in ball shavings... Ooooops.

-RC

We let RC know, and they were great enough to take back some of the boards and provide replacements. I'm personally more worried about the conformal coating; the amount of robot "residue" on our roborio right now is crazy. If we didn't coat the gyro, I'm sure it would have shorted by now (I'll take pictures next time I'm with the bot).

The ball shavings are probably not conductive so should not cause shorts but if some smaller particles get into the sockets, it could cause poor or intermittent connections. Not quite as bad as a short but still not good.

It might be worth considering installing the Roborio, PDP, VRM and PCM on vertical surfaces so they don't naturally accumulate debris.
