+description: |
+  6-axis MotionTracking device that combines a 3-axis gyroscope and a 3-axis accelerometer.
+
+  It has a configurable host interface that supports I3C, I2C and SPI serial communication, features a 2kB FIFO and
+  2 programmable interrupts with ultra-low-power wake-on-motion support to minimize system power consumption.
+
+  Other industry-leading features include InvenSense on-chip APEX Motion Processing engine for gesture recognition,
+  activity classification, and pedometer, along with programmable digital filters, and an embedded temperature sensor.
