This is GY-87 MPU-9265 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 MPU6500 accelerometer and gyro chip, and HMC5883L digital compass.
There are different types of magnetometer are available; the basic differences between MPU6000, MPU6050 and MPU6500 is:
|1. The sampling rate of 8 kHz.||1. Sampling Rate 8 KHz.||1. Sampling Rate 32 KHz.|
|2. Supports SPI and I2C interface. But I2C is too slow to handle 8 kHz gyro update.||2. Supports I2C interface communication protocol.||2. Supports both I2C and SPI interface.|
|3. Vibration Sensitivity is better than MPU6500.||3. Vibration Sensitivity is better than MPU6500 but the speed of operation is less than MPU6000.||3. It is more susceptible to vibrations, so the need for some vibration isolation method.
It is faster than both MPU.
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°compass heading accuracy. Applications for the HMC5883 include Mobile Phones, Netbooks, Consumer Electronics, Auto Navigation Systems, and Personal Navigation Devices.
