Blackberry trackball sensor Mouse trackball Hall effect sensor 360°trackball module
Regarding LC-EM-1279
The trackball module is designed and manufactured using BlackBerry trackballs,
The module can drive the X and Y direction shafts through roller motion,
and the corresponding SMD Hall elements are signaled by the multipole magnetizing magnet fixed on the shaft to determine the motion trajectory.
A small SMD switch is also designed below the trackball, making it convenient for users to trigger events or "click" selections.
