MPU-9150 Triple Axis Accelerometer Gyroscope Magnetic Field Sensor

This breakout board makes it easy to prototype with the InvenSense MPU-9150 by breaking out all the pins you need to standard 0.1″ spaced headers. The board also provides I2C pullup resistors and a solder jumper to switch the I2C address of the device.

The MPU-9150 is a System in Package (SiP) that combines two chips: the MPU-6050, which contains a 3-axis gyroscope, 3-axis accelerometer, and an onboard Digital Motion Processor (DMP) capable of processing complex 9-axis MotionFusion algorithms; and the AK8975, a 3-axis digital compass. The part’s integrated 9-axis MotionFusion algorithms access all internal sensors to gather a full set of sensor data. The part is offered in a 4x4x1mm LGA package and is upgrade-compatible with the MPU-6050 integrated 6-axis MotionTracking device, providing a simple upgrade path and making it easy to fit on space constrained boards.
