MIU-B02A
MEMS Inertial Measurement Unit
Product Overview
MIU-B02A is a high-reliability, cost-effective six-axis high-precision MEMS inertial sensor. This compact IMU captures angular rate and acceleration data of the carrier in real time, serving as the core sensing component for inertial navigation, attitude stabilization and dynamic measurement systems. It adopts a domestic MEMS chip scheme and meets lightweight integration requirements for various small unmanned platforms.
Core Technical Advantages
It integrates full-temperature calibration compensation from -45℃ to +80℃ and a multi-sensor redundant fault-tolerant architecture, supporting online firmware upgrade. It steadily outputs raw sensing data under severe vibration and shock conditions, featuring compact size, light weight and low power consumption. As a high-performance MEMS inertial sensor, it is well suited for space-limited embedded projects.

This compact IMU is designed for integration scenarios with limited installation space. It delivers clean and stable raw sensing data and can be directly connected to navigation solving boards. When GNSS signals are denied, it continuously outputs reliable attitude data, making it a preferred inertial sensor solution for small unmanned systems and electro-optical stabilization platforms. We provide driver support, secondary development service and customized calibration upon request.
