This is GY-87 MPU-9250 3-axis 9-DOF Attitude Gyro Magnetometer Accelerator Sensor Module. GY-87 MPU-9250 9 axis attitude gyro is a 9 degree of freedom (DOF) device which incorporates an MPU6050 accelerometer and gyro chip, and HMC5883L digital compass.

MPU6050 :

The MPU6050 devices combine a 3-axis gyroscope and a 3-axis accelerometer on the same silicon together with an on board Digital Motion Processor (DMP) capable of processing complex 9-axis Motion Fusion algorithms.

The parts integrated 9-axis Motion Fusion algorithms access external magnetometers or other sensors through an auxiliary master I2C bus, allowing the devices to gather a full set of sensor data without intervention from the system processor. Are the devices offered in the same 4x4x0.9 mm QFN footprint and pinout as the current MPU-3000 the family of integrated 3-axis gyroscopes, providing a simple upgrade path and making it easy to fit on space-constrained boards.

The InvenSense Motion Apps Platform that comes with the MPU-6050 abstracts motion-based complexities, offloads sensor management from the operating system and provides a structured set of APIs for application development. For precision tracking of both fast and slow motions, the parts feature a user-programmable gyro full-scale range of +/- 250, 500, 1000, and 2000 degree/sec (DPS) and a user-programmable accelerometer full-scale range of +/- 2g, 4g, 8g, and 16g.

HMC5883 :

The HMC5883 is a surface mount multi-chip module designed for low field magnetic sensing with a digital interface for applications such as low cost compassing and magnetometry. The HMC5883 includes our state of the art, high-resolution HMC118X series magneto-resistive sensors plus Honeywell developed ASIC containing amplification, automatic degaussing strap drivers, offset cancellation, 12-bit ADC that enables 1 to 2 Degree compass heading accuracy. Applications for the HMC5883 include Mobile Phones, Netbooks, Consumer Electronics, Auto Navigation Systems, and Personal Navigation Devices.
