Description:

This is our Blackberry Trackball Breakout Board. The four spindle trackballs have a tiny round magnet on the end; each of these paired SMD Hall effect sensors for measuring up, down, left, and right movement of the trackball. A kind of patch momentary switch is placed on the trackball to give you a selector switch. The button will pull down when the switch is pressed.
 
The trackballer also includes 4 LED lights: red, blue, green and white. These can be used to clear the light on the trackball in any color you can imagine.
 
All features are broken out with a 0.1" pitch head. 2.5-5.25vdc power adjustment, must be supplied with power hall sensor. Trackball attached with strong calcium adhesive. Board is shown with all components filled.
 
The combination of Hall effect sensor and trackball is surprisingly sensitive. A slight roll of the trackball will create multiple high/low transitions on the 4-axis pin, easily picking up any microcontroller basically giving you the option of adding a mouse to your project. 360° rotation of the trackball along one axis will result in approximately 9 high/low transitions.
