Note:

① Module horizontally stationary for 2 hours.

② The module was measured after 1 hour of movement on an indoor robot, 1σ

③ After geomagnetic calibration, the product needs to be configured in AHRS mode when there is no magnetic field interference in the surrounding area.

④ The turntable rotates continuously for 10 turns, and the heading angle accumulates error.
