    Introduction

    ER-MIMU-01/01Mini North-Seeking MEMS IMU

    Introduction
    Inertial Measurement Unit, referred to as IMU, is a device to measure the attitude angle (or angular velocity) and acceleration of the three axis of the object. Gyroscope and accelerometer are the core devices of inertial navigation system (INS). With the built-in accelerometer sensor and gyroscope, the IMU can measure the linear acceleration and rotation angular velocity from three directions and can obtain the attitude, velocity and displacement information of the carrier through the resolving.

    ER-MIMU-01/01Mini uses MEMS accelerometer and gyroscope with high quality and reliability, RS422 and external communication, default baud rate 921600 (customized). With X, Y, Z three-axis precision gyro, X, Y, Z three-axis accelerometer with high resolution, can be output by RS422 X, Y, Z three axis of gyroscope and accelerometer’s original hexadecimal complement data (including gyro hexadecimal complement the numerical temperature, angle, the accelerometer hexadecimal temperature, the acceleration hexadecimal complement number); It can also output float dimensionless values of the gyroscope and accelerometer processed by the underlying calculation.

    A simple operation is required to connect our products to your system and obtain IMU data without the 15-pin plug provided by our company. At the same time, the size and weight of our products can be significantly reduced by removing the base plate housing.
