1 General Description
EasyPoint™ N40P112 is a miniature joystick module concept based
on contact-less, magnetic movement detection. The integrated two-
dimensional linear encoder monitors the movement of the magnet
incorporated in the knob and provides directly the x and y
coordinates via I²C output. An integrated mechanical push button
built in the module provides a “select” function.
