Introduction

ER-MIMU-M01B Low Power Consumption MEMS IMU

Introduction
The ER-MIMU-M01B Low Power Consumption MEMS IMU is a general-purpose, miniaturized component that contains three-axis gyroscope and three-axis accelerometer information. Temperature compensation is performed through the bias stability and scale of each axis to improve its measurement accuracy.

Features
Miniaturized IMU
Low power consumption
High cost performance
Total temperature compensation
Gyro bias instability: ≤3°/h
Gyro bias stability (1σ): ≤12°/h
Accelerometer bias instability: ≤0.04mg
Accelerometer bias repeatability (1σ): ≤0.3mg

Application
Inertial navigation: inertial guidance, integrated navigation, platform stability
Short-term navigation: flight control, ballistic correction, telemetry and remote control
Attitude control: UAV, antenna orientation
