I hadn't seen this one before. It appears to support quite a few 
devices. From looking at their Spatial 3/3/3 driver, it's based on the C 
API, and it defines a custom message for it. In comparison, mine has an 
object-oriented structure, and adheres to the ROS API better (standard 
IMU message and topics, calibration services, params, etc).

My stack is partly based on Tully's work. He uses an older version of 
the C API, and supports different devices. I'm not sure if he still 
maintains the stack. I've updated the C API installer to the latest 
version released from phidgets.

Cheers,
