Communication link interface provides a standard I2C, can return axis attitude information (Roll, Pitch, and Yaw). Triaxial acceleration device RAW data, three-axis magnetometer RAW data, single-axis gyroscope RAW data, and temperature information.

The figure is a smart sensor lite various axial, and read out the direction of quality. Arrow direction is positive direction, XY plane is horizontal, Z axis is vertical when the direction Pitch:This is the board with the level of X-axis angle, the output value is -180 to +180, the unit is the point of view Roll:This is the board level with the angle between Y axis, the output value is -180 to +180, the unit is the point of view Heading (Yaw):This is the board X-axis with the angle between magnetic north, the output value is 0 to 360 units of angle, clockwise to increase value
Pitch, Roll, Heading (Yaw) is the accelerometer with the magnetometer on the MCU through the smart sensor signal filtering done, go through orientation calculus computed from Ted - Brian angle(Tait-Bryan angles ), a clear description of Now the body orientation in 3D space
Gyro output value is the angular velocity after filtering the output signal, turn the Z axis shaft is a board, the output value of -300 to +300, the units are degrees / second, counterclockwise direction is positive Oh!!
