Introduction

Grove - IMU 10DOF is a combination of Grove - IMU 9DOF and Grove - Barometer Sensor (BMP180). This module is base on MPU-9250 and BMP180, 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 BMP180 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.
