Product Features

1. The module integrates high-precision gyroscope, accelerometer and geomagnetic field sensor, adopts high-performance microprocessor, advanced dynamic solution and Kalman dynamic filtering algorithm, and can quickly solve the current real-time motion posture of the module.
2. Advanced digital filtering technology can effectively reduce measurement noise and improve measurement accuracy.
3. The interior of the module is integrated with the atude solver, which can accurately output the current attitude of the module in the dynamic environment with the atitude measurement accuracy of 0.2u00b0; extremely high stability and even better performance than some professional tllers.
4. The z-axis heading angle is added with the filtering fusion of geomagnetic sensor, which solves theaccumulated error caused by the drift of gyroscope integral in the 6-axis algorithm, and can stably output the heading angle data for a long time.

Note: due to magnetic field dletection, calibration is required before use, and the distance between hard and magnetic objects such as magnetic interference area, electronic equipment, magnet, loudspeaker, etc. should be at least 20cm.
5. Working current: u224816mA, standby current 14uA-16uA. data Interface: baud rate 115200.
6. The output content can be selected at will, data output frequency: 0.2Hz - 200Hz,50Hz - 200Hz data package transmission, default 10Hz.
7. Four extended ports are reserved and can be configured as analog input, digital input, and digital output.
8. It adopts the gold plating process of stamp holes and can be embedded into the PCB board of users.

Note: The baseboard should be added or embedded into other PCB boards, and the wiring under the geomagnetic chip should not be conducted to avoid interfering with the magnetometer.
9. 4-layer PCB board technology, thiner, smaller and more reliable.
bluetooth 5.0: supports Android /OS operating systems (for actual use, the final device shall prevail)
