broken gyro?

[hrldcpr]

hi all,

i think our gyro or some part of our gyro board may be broken, but i want to be somewhat sure before we try to order a new one.

here are some clues:

* the resistance between supply and ground on the board (when unplugged) is 8.7kΩ -- should it be higher? what is it on a known-good board?

* when i do plug it in (to the crio analog), the voltage between supply and ground gets pulled to -0.76V, whereas it should be +5V! (this number seems suspiciously similar to a diode voltage drop but i don't understand if or why that might be relevant.)


we're definitely connecting the power and ground and signal to the proper places. and the soldering checks out too, unless a very slight short could somehow be providing the 8.7kΩ path between power and ground?

thanks for any help!
