That's only a two axis accelerometer.

davidrfoley:
You are correct, we have put two Accelerometers on the PCB, and have an optional 2nd I2C bus connection to allow for the connection of separate orientation of the off board accelerometer.  This allows for full 3D motion tracking.  The boards supports both the MEMSIC part and the Analog ADXL322JCP-ND on the main PCB, and a second MEMSIC part on the offboard I2C bus.

ChadTower:

Elaborate.  Why so complex for simple nudge functionality?

davidrfoley:
The design was done so that for low cost applications you could just use a single chip.  For more accuracy you could simply add a chip.  We designed it around the idea that you may want full rotational values for all axis on higher end implementations, and just simple nudging in lower end.  The design is scalable, and the extra fiberglass on the PCB is almost no cost.

ChadTower:

Oh I read that desc as two on board and one optional off.  I couldn't figure out why you would put in three of them.
