Introduction

ER-MIMU-02 High Performance Navigation MEMS IMU

Introduction
Inertial Measurement Unit (IMU) is a device that measures an object's three-axis attitude angle (or angular velocity) and acceleration. Gyroscopes and accelerometers are the core devices of an Inertial Navigation System (INS). Through the built-in accelerometers and gyroscopes, the IMU can measure the three-axis linear acceleration and three-axis rotational angular velocity, and obtain the attitude, velocity, and displacement information of the carrier through analysis.

ER-MIMU-02 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.
