MPU9250

The MPU9250 is a System in Package (SiP) that includes a 3-axis gyroscope, a 3-axis accelerometer, and a 3-axis magnetometer. It is manufactured by InvenSense, a TDK Group company. This integrated sensor module is designed for motion tracking and sensing applications. The gyroscope measures angular velocity, the accelerometer measures linear acceleration, and the magnetometer measures magnetic field strength. These three sensors are crucial for determining the orientation and movement of an object.

The MPU9250 offers a combined digital output via an I2C serial interface. It is known for its low power consumption and compact size, making it suitable for a wide range of embedded systems. The device integrates InvenSense's MotionFusion™ technology, which combines data from the gyroscope, accelerometer, and magnetometer to provide a more accurate and stable estimation of orientation. This fusion of data helps to overcome the inherent limitations of individual sensors, such as drift in gyroscopes and noise in magnetometers.

Applications for the MPU9250 include drone stabilization, virtual reality and augmented reality headsets, gaming controllers, and inertial navigation systems. Its ability to provide comprehensive motion data in a single chip simplifies hardware design and reduces component count. The MPU9250 is widely available on development boards and breakout modules, facilitating its use by hobbyists and professional engineers alike.
