I have a roborio that my students installed. Our first problem was that when we hooked it up, it blew the fuse on the Rev Robotics power distribution panel. As a typical troubleshooting step, we vacuumed out the Robo Rio and then blew it with compressed air. We did find a few aluminum filings in the Roborio, and we saw one improvement.
Where, before, the resistance between the two pins on the power input was close to zero, which seemed odd, now the resistance between the two pins is infinite.
What was more concerning was that, when I took the roborio out of its case, it became clear that one of my students screwed two of the mounting bolts in too far, went through the plastic protecting the board, and then may have damaged the board itself.
Should I try hooking the roborio up to see if it still works? I am a bit concerned about the amount of damage I saw on the board. It looks like a small capacitor may have been moved a bit. It is possible it still makes electrical contact, and thus might work, but it seems a bit sketchy. I have included a picture.
Please advise.
