Grove - IMU 9DOF v2.0

Grove - IMU 9DOF v2.0 is an upgrade version of Grove - IMU 9DOF v1.0 and it is a high performance 9-axis motion tracking module, which is base on MPU-9250. The MPU-9250 is a integrated 9-axis motion tracking device designed for the low power, low cost, and high performance requirements of consumer electronics equipment including smartphones, tablets and wearable sensors. MPU-9150 features three 16-bit ADC for digitizing the gyroscope outputs and three 16-bit ADCs for digitizing the accelerometer outputs and three 16-bit ADCs for digitizing the magnetometer outputs.


Interface Function


Based on library,we can display value of Accel&Gyro&Magnet on serial monitor. Now let's show how to use the module.

Hardware Installation

Hardware installation is very easy, because there's an I2C Grove in Seeeduino, so what we need to do is connect it to I2C Grove via a Grove cable.

Software Part

In static state,the z-Axis output value is about 0.98g,so you can refer to this to test if your sensor can work normally.
Orientation of Axes
The diagram below shows the orientation of the axes of sensitivity and the polarity of rotation.Note the pin 1 identifier (•) in the figure.
