MPU-9250 9-Axis Attitude Gyro Accelerator Magnetometer Sensor

The MPU-9250 is a 9-axis motion tracking device that combines a 3-axis gyroscope, 3-axis Accelerometer, 3-axis magnetometer and a Digital motion processor. Based on the IC MPU-9250, the world’s smallest 9-axis MotionTracking device and incorporates the latest InvenSense design innovations, this module features three 16-bit ADCs for digitizing the gyroscope and three 16-bit ADCs for digitizing the accelerometer outputs and three 16-bit ADCs for digitizing the magnetometer outputs.

Low power, low cost, and high performance make it suitable for consumer electronics, including smartphones, tablets and wearable sensors.
