Examples include the FSM-SENS-1, a 6-axis sensor-only module that integrates with an external Freespace MotionEngine, and the FSM-SI-2, which combines the Freespace MotionEngine on an embedded microprocessor along with a 3-axis digital gyroscope, 3-axis digital accelerometer and optional 3-axis magnetometer (compass) to provide high-performance, calibrated motion data for a variety of applications.
