Interfaces and connection options Serial port and IIC two digital interfaces for flexible connections. Serial port baud rate adjustable from 2400 bps to 921600 bps; IIC interface supports fullspeed 400 kHz. Attitude solving and accuracy Attitudes solvers are integrated in the module and, with the dynamic Kalman filter algorithm, provide accurate output in dynamic environments. Attitudes measurement accuracy is 0.01 degrees, with stability and performance that can exceed professional inclinometers. Sensor suite and processing power JY901 series module integrates gyroscopes, accelerometers and geomagnetic field sensors. It uses a performance microprocessor and advanced dynamic calculation and Kalman dynamic filtering algorithms to rapidly determine the module's motion postures. Power, voltage, and compatibility The module has its own voltage stabilizing circuit. Working voltage is 3V6V, and pin levels are suitable for 3.3V/5V. Use scenarios and applications Drone attitude and orientation control for stable flight and precise maneuvering. Robotics motion tracking and pose estimation for autonomous or remotely operated systems. Wearable motion sensing for sports performance analysis or VR/AR applications.
