LC-EM-1279

Product Name

Blackberry trackball sensor Mouse trackball Hall effect sensor 360°trackball module

Regarding LC-EM-1279

The trackball module is designed and manufactured using a BlackBerry trackball. The module can drive the X and Y direction axes through the movement of a roller.
By rotating the multi-level magnetized magnet fixed on the axis, it sends signals to the corresponding SMD Hall elements to determine the motion trajectory.
A small SMD switch is also designed below the trackball for users to trigger events or "click" to select
