Grove IMU 10DOF v2.0

Grove-IMU 10DOF v2.0 is a upgrade version of Grove-IMU-10DOF， which replace BMP180 with BMP280. As the successor to the widely adopted BMP180, the BMP280 delivers high performance in all applications that require precise pressure measurement. This module is base on MPU-9250 and BMP280, the MPU-9250 is a 9-axis MotionTracking device that combines a 3-axis gyroscope, 3-axis accelerometer, 3-axis magnetometer and a Digital Motion Processor(DMP), and BMP280 is a high precision, ultra-low power digital pressure sensors for consumer applications. This module is very suitable for the application of smartphones, tablets and wearable devices.

Hardware Overview

MPU-9250 I2C address select Pad, default connected a and b address is 0x68, if connect b and c address is 0x69
MPU-9250 interrupt pin, the interrupt should be configured, available interrupt sources are: motion detection, fifo overflow, data ready, i2c master error
Orientation of Axes:
The diagram below shows the orientation of the axes of sensitivity and the polarity of rotation.
The BMP280 is an absolute barometric pressure sensor especially designed for mobile applications. The sensor module is housed in an extremely compact 8-pin metal-lid LGA package with a footprint of only 2.0 × 2.5 mm2 and 0.95 mm package height. Its small dimensions and its low power consumption of 2.7 μA @1Hz allow the implementation in battery driven devices such as mobile phones, GPS modules or watches.

Getting Started

Connections

Here we will show you how this Grove - IMU 10DOF V2.0 works via a simple demo. First of all, we need to prepare the below stuffs:

Connect Grove - IMU 10DOF v2.0 to I2C port of base shield.
Plug the base Shield into Arduino.
Connect Arduino to PC by using a USB cable.

Software

Download the Grove-IMU_10DOF_v2 library.
Please follow how to install an arduino library procedures to install library.
Restart the Arduino IDE. Open “ IMM_10DOF_Test example via the path: File -> Example ->GROVE_IMU_10DOF_V2-master-> IMU_10DOF_V2_Test.
Upload the code. Note that we should select the correct board type and COM port.
We can see:
