Introduction

ER-AMM-2 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 ER-AMM-2 attitude measurement module. With the built-in accelerometer sensor and gyroscope, ER-AMM-2 can measure the linear acceleration and rotation angular velocity from three directions and can obtain the attitude, velocity.

ER-AMM-2 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 data without the 15-pin plug provided by our company.
