Product manual

Product Introduction

The GMU100-BL is a Bluetooth attitude sensor (AHRS miniature attitude reference system) designed for dynamic balancing applications in model aircraft, drones, robots, agricultural machinery, engineering vehicles, and forklifts, offering excellent cost-effectiveness. This product integrates data from a three-axis accelerometer, a three-axis magnetometer, and a three-axis gyroscope, supplemented by a temperature compensation algorithm and Kalman filtering for data fusion, enabling real-time attitude information output. Thanks to this technical architecture, the product maintains stable response performance and timeliness across the entire attitude range, making it suitable for various motion attitude monitoring applications. In addition to attitude data, the sensor supports outputting raw data across nine axes: three-axis acceleration, three-axis angular velocity, and three-axis magnetic field. Users can modify and expand system operating parameters to adapt to different application platforms.

The product incorporates on-chip Flash IAP (in-circuit programming) technology, allowing users to save configuration parameters as needed, retaining the memory even after power loss. Data output methods include a USB 2.0 wired interface and Bluetooth wireless transmission (supporting Bluetooth 5.1 and BLE protocols). It integrates 2.4GHz adaptive frequency hopping technology, which can achieve stable transmission within a 40-meter line-of-sight range in unobstructed environments. It also supports firmware upgrades and multi-device networking synchronization, which helps to improve the convenience and flexibility of deployment in industrial sites and facilitates secondary development and application expansion for users.
