Re: broken gyro?

I agree that it seems bizarre for the voltage to get pulled negative, but that's definitely what's happening according to my multimeter: the voltage between supply and ground on the analog breakout is +5V before I attach the gyro board, but then -0.76V when the gyro board is attached.

I am doing all of this at a work table, i.e. none of it is mounted to the robot and the board isn't touching anything conductive.

The green LED stays lit on the analog breakout the whole time. I haven't checked whether the other supply voltage pins also get pulled negative, and unfortunately I'm not with the electronics right now.
