 This document describes the setup requirements for demonstration of I2C communication on the hardware platform 
 [EV74H48A](https://www.microchip.com/en-us/development-tool/EV74H48A) "Curiosity Platform Development Board" and [EV02G02A](https://www.microchip.com/en-us/development-tool/EV02G02A) "dsPIC33AK128MC106 General Purpose Dual In-Line Module (DIM)" using MPU9250 sensor on the MPU 9DOF Click Board.</p>
 
-MPU-9250 is a multi-chip module (MCM) with 9-axis MotionTracking device that combines a 3-axis gyroscope, 3-axis accelerometer, 3-axis magnetometer and a Digital Motion Processor™ (DMP). This example uses all the three sensors to estimate the roll, pitch and yaw angles.
