    Overview

    1. The module integrates high-precision gyroscopes and accelerations, and uses high-performance microprocessors and advanced dynamics calculation and Kalman dynamic filtering algorithms to quickly solve the current real-time motion posture of the module.

    2. Using advanced digital filtering technology, it can effectively reduce measurement noise and improve measurement accuracy.

    3. An attitude solver is integrated inside the module, and combined with the dynamic Kalman filter algorithm, it can accurately output the current attitude of the module in a dynamic environment. The attitude measurement accuracy is statically 0.2°, the stability is extremely high, and the performance is even better than some professional ones. Inclinometer.
