    Introduction

    Miniaturized MEMS IMU

    Introduction
    The product is mainly composed of three-axis MEMS accelerometer and gyroscope. The working principle is as follows: the gyroscope and accelerometer data are collected by ARM microcontroller, three high-precision gyroscopes are collected by 1-channel digital interface SPI, and three accelerometers are collected by another 1-channel digital interface SPI. All sensors are calibrated and compensated in software after acquisition.
