High-Precision IMU AHRS Attitude Sensor

Product Overview

The High-Precision IMU AHRS Attitude Sensor is an all-in-one attitude measurement solution built for robotics developers, drone engineers, and embedded system designers, eliminating the need to develop and debug complex attitude estimation, filtering, and sensor fusion algorithms from scratch. It features a built-in high-performance 32-bit processor with integrated Mahony filtering and AHRS attitude fusion algorithms, delivering 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 and is fully compatible with microcontrollers, Linux host controllers, and ROS1/ROS2 systems — making it an ideal choice 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 directly output fully calibrated attitude data, including Euler angles, quaternions, acceleration, angular velocity, and more — saving hundreds of hours of algorithm development and tuning. X/Y-axis static accuracy reaches 0.05°, and Z-axis heading drift is <0.05°/h, ensuring stable and reliable data.
Flexible Configuration Options

Three configurations available to meet your project needs: 6-axis VRU (gyroscope + accelerometer) for cost-sensitive applications requiring only dynamic pitch/roll response; 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 baseboard — compatible with all major development platforms, plug-and-play with no driver installation required.
Broad Host Controller Compatibility

Ready to use out of the box with all microcontrollers (STM32/ESP32/Arduino/RP2040), Linux host controllers (Raspberry Pi/Jetson/RDK series), Windows/macOS PCs, and natively supports ROS1/ROS2 systems with pre-written example code provided.
Ultra-Compact & Low Power

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