How much noise are you getting, and is it evenly distributed on all three axis?

Our molded cable and ribbon cable are the same length so perhaps it is the length causing issues. Minimizing the length from the sidecar to the sensor becomes important I reckon.
The noise is everywhere. Some of it is just LSB noise, some of it is 'real' vibration and some may be power/ground related. We need to hard mount ours so the vibrations are beyond the bandwidth of the sensor. Hopefully this (and some filter caps) will help. I think we might filter the data to make it usable. The drift of the zero G setpoint is more troublesome. We plan on resetting the V and D sums when the wheel encoders say the robot is sitting still.
