High-Precision IMU AHRS Attitude Sensor

Product Overview

The High-Precision IMU AHRS Attitude Sensor is an all-in-one attitude measurement solution designed for robotics developers, drone engineers, and embedded system designers, eliminating the need to develop and tune complex attitude estimation, filtering, and sensor fusion algorithms from scratch. Equipped with a built-in high-performance 32-bit processor, integrated Mahony filtering and AHRS attitude fusion algorithms, it directly outputs calibrated attitude data (Euler angles, quaternions, acceleration, angular velocity) at up to 100Hz refresh rate. Available in 6-axis (VRU), 9-axis (AHRS) and 10-axis (AHRS + barometer) configurations, it supports I2C/UART/Type-C communication, is fully compatible with microcontrollers, Linux main controllers and ROS1/ROS2 systems, making it ideal for robotic motion control, drone attitude stabilization, intelligent navigation, and motion tracking applications.

Key Advantages

No Custom Algorithm Required

Built-in Mahony filtering and AHRS sensor fusion algorithms output fully calibrated attitude data directly, including Euler angles, quaternions, acceleration, angular velocity and more, saving hundreds of hours of algorithm development and tuning time. X/Y axis static accuracy up to 0.05°, Z-axis heading drift <0.05°/h, ensuring stable and reliable data output.
Flexible Configuration Options

Choose from 3 configurations to match your project requirements: 6-axis VRU (gyro + accelerometer) for cost-sensitive dynamic response applications, 9-axis AHRS (adds magnetometer) for full 3D attitude measurement with heading data, 10-axis AHRS (adds barometer) for 3D position tracking with altitude measurement.
Multi-Interface Support

Supports I2C and UART communication via pin headers, or Type-C USB communication via optional base board, compatible with all mainstream development platforms, plug-and-play with no driver installation required.
Wide Main Controller Compatibility

Works out of the box with all microcontrollers (STM32/ESP32/Arduino/RP2040), Linux main controllers (Raspberry Pi/Jetson/RDK series), Windows/macOS PCs, and native support for ROS1/ROS2 with pre-written sample code.
Ultra-Compact & Low Power

Tiny 27.4×22.6×12mm form factor weighing only 3.8g, operating current of just 11mA, perfect for integration into space-constrained robotic and drone projects with strict power budgets.
