2.4.4 Gyroscope, Accelerometer, and Compass

The MPU-9250 device is a multichip module consisting of a 3-axis gyroscope, a 3-axis accelerometer, and a 3-axis magnetometer for position tracking (see [4]). The MPU-9250 features three 16-bit ADCs each for the gyroscope, accelerometer, and magnetometer. Some other features of the MPU-9250 are as follows:

  • High-precision clock
  • Precision tracking of fast and slow motions
  • VDD operating range of 2.4 V to 3.6 V
  • I2C and SPI serial communication interface
