MPU9550MPU9255

The MPU9550 and MPU9255 are integrated 9-axis Motion Tracking devices developed by InvenSense. These devices combine a 3-axis gyroscope, a 3-axis accelerometer, and a 3-axis magnetometer into a single System in Package (SiP). They are designed for applications requiring precise motion sensing, such as smartphones, drones, virtual and augmented reality systems, and inertial navigation.

The MPU9255 is an enhancement over previous generations, offering improved performance and features. The MPU9550 is a similar device within the InvenSense portfolio. Both devices utilize InvenSense's proprietary MotionFusion™ technology to deliver accurate sensor readings. The integrated sensors provide data on angular velocity, linear acceleration, and magnetic field strength, which can be fused to determine the orientation and movement of an object in three-dimensional space.

These sensors typically communicate with a host microcontroller via an I2C or SPI interface. They are known for their low power consumption, making them suitable for battery-powered devices. The small form factor and comprehensive motion sensing capabilities make the MPU9550 and MPU9255 popular choices for a wide range of consumer and industrial electronics where advanced motion tracking is a key requirement. Developers often utilize these chips to create more immersive and responsive user experiences in devices that interact with the physical world.
