Introduction

MPU-9150 is the world's first nine-axis Motion Tracking components designed for low-power, low-cost, high-performance consumer electronics products as smart phones, tablet, wearable sensors and other devices. GY-9150 Module integrates MPU6050 (three-axis gyroscope + tri-axial accelerometer) and AK8975 three-axis digital electronic compass on one chip, simplifying the hardware circuit, reducing the PCB size. In addition, it contains a DMP (Digital Motion Processor) that can process 9-axis sensor component fusion algorithms and a run-time calibration firmware. GY-9150 Module can help customers eliminate troubles of signals-regulating, combining fusion algorithms technology and factory calibration when choosing different brands of Motion Tracking components.
