a new 6 axis IMU

Hi guys,

I’m building a really small AUV (autonomous underwater vehicle), and I’m going to put a six axis IMU inside it. The space available is in the nosecone, and it is a cylinder 0.75" diameter and 1" long.

Now, I can fit in there:

  • 5 DOF breakout board

  • ADXRS breakout board, upside down, below it

  • small custom board with I2C 12 bit 12 channel A/D, plus a honeywell 2 axis digital compass sensor (HMC6352). I have to use a voltage divider on the ADXRS rate output, since its 5 volts, and everything else is 3.3 volts, but that’s no big deal

I may replace the 2 axis compass chip with a 3-axis mag, and just do the whole integration thing on the ARM with a Kalman filter.

Anyways, it would be cool if you could take your 5 DOF breakout board, and add an ADXRS to the bottom of that board…
