Description of product

Description

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:

MPU6000MPU6050MPU6500
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.

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°compass heading accuracy. Applications for the HMC5883 include Mobile Phones, Netbooks, Consumer Electronics, Auto Navigation Systems, and Personal Navigation Devices.
