Overview

1. The module integrates high-precision gyroscopes, accelerometers, and geomagnetic field sensors. It uses high-performance microprocessors and advanced dynamic calculation and Kalman dynamic filtering algorithms to quickly solve the current real-time motion posture of the module. It has It has the advantages of wide measurement range, excellent noise immunity, no hysteresis, and stable temperature characteristics.

2. The use of advanced digital filtering technology 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 0.001°, the stability is extremely high, and the performance is even better than some professional inclination angles. instrument!

4. The module has its own voltage stabilization circuit, with an operating voltage of 5V~36V.

5. Support 485, CAN and other digital interfaces. It is convenient for users to choose the best connection method. The serial port rate is adjustable from 4800bps to 230400bps.

6. In the case of magnetic field interference, it will automatically switch to crystal gyroscope integral calculation to ensure that there is no sudden change in heading angle and reduce cumulative errors.

7. P67 level protection, aluminum shell, strong resistance to external electromagnetic interference, stable performance, and can adapt to long-term work in harsh industrial environments.
