Sense.I.9
digital 9-DOF IMU
The Sense.I.9 embeds the TDK Invensense ICM20948 IMU with a co-packaged 6-DOF IMU and a 3-DOF magnetic compass. The triaxial accelerometer has a configurable 16-bit full-scale range from +/-2g to +/-16g with an output data rate up to 4.5 kHz, while the triaxial rate gyroscope has a 16-bit full-scale range from +/-250 to 2000 degrees per second with an output date rate up to 9 kHz. The triaxial magnetic compass has a 16-bit full-scale range of +/-4900µT with an output data rate of up to 100 Hz. The sensor includes configurable filters and an on-board motion processor.

Application Notes
Sensor Axes
The IMU and compass origins are colocated, with the axes aligned at the center of the IC, which is at (-0.2, -0.2) mm relative to the center of the tile. The Z axis of all sensors extends from the top surface of the tile, while the X axis points up between pads 1 and 10, as shown here.
Pad Assignments
