This is a breakout board for our Blackberry Trackball. The four
the trackball have a tiny circular magnet the end; each of these are
an SMD hall effect sensor, which are used to measure up, down, left and
movements of the trackball. An SMD momentary switch is placed under the
trackball to give you a select switch. The BTN line will be pulled low
switch is pressed.
Also included on the Trackballer are 4 LEDs: red, blue, green and white. These can be powered to light the clear trackball up any color you can imagine.
All features are broken out to a 0.1" pitch header. Regulated, 2.5-5.25VDC power must be provided to power the Hall sensors. The trackball is attached with strong CA glue. Board comes as shown, with all components populated.
The hall-effect sensors and trackball combo are surprisingly
slight roll of the trackball creates multiple high/low transitions on
axis pins, easily picked up by any microcontroller. A 360° rotation of
trackball, along a single axis, will result in about 9 high/low
