Features: JY901 series module integrate gyroscopes, accelerometers and geomagnetic field Sensors, and adopt high-performances microprocessors and advanced dynamic calculation and Kalman dynamic filtering algorithms to quickly solve motion postures of the module. The advanced digital filtering technology can effectively reduce the measurement noise and measurement accuracy. The attitude solvers is integrated in the module, and with the dynamic Kalman filter algorithm can be accurately output in a dynamic environment, with attitude measurement accuracy of 0.01 degrees, high stability and even better performances than some professional inclinometers! The module have its own voltages stabilizing circuit, working voltages is 3v-6v, pin level is suitable of 3.3V/5V, and the connection is convenient. Support serial port and IIC two digital interfaces. It is convenient for users to choose a good connection. The serial port rate is adjustable from 2400bps to 921600bps, and the IIC interfaces supports full-speed 400K rate.
