  • Overview

    1. The module integrates high-precision gyroscopes, accelerometers, and geomagnetic field sensors, and uses high-performance microprocessors and advanced dynamic calculations and Kalman dynamic filtering algorithms to quickly solve the current real-time motion posture of the module.

    2. The module integrates an attitude solver and cooperates with the dynamic Kalman filter algorithm to effectively reduce measurement noise and improve measurement accuracy. It can accurately output the current attitude of the module in a dynamic environment, with an attitude measurement accuracy of 0.2° and extremely high stability, even better than some professional inclinometers.

    3. The output content can be selected arbitrarily, and the data output frequency is 100HZ by default.

    4. Four expansion ports are reserved, which can be configured as analog input, digital input, digital output and other functions.

    5. Using stamp hole gold plating technology, it can be embedded in the user's PCB board. 4-layer PCB board technology is thinner, smaller, and more reliable.

    6. Bluetooth 2.0: supports Android/IOS operating system (actual use is subject to the final device)
