MPU-9250 Hookup Guide
The MPU-9250 is the latest 9-axis MEMS sensor from InvenSense®. This replaces the popular EOL'd MPU-9150. InvenSense® lowered power consumption and decreased the size by 44% compared to the MPU-9150. "Gyro noise performance is 3x better, and compass full scale range is over 4x better than competitive offerings." The MPU-9250 uses 16-bit analog-to-digital converters (ADCs) for digitizing all 9 axes.
The System in Package (SiP) combines two chips: the MPU-6500, which contains a 3-axis gyroscope, a 3-axis accelerometer, and the AK8963, a 3-axis magnetometer.
