Trajectory Ball Module ICSH044A
- Operating Voltage: 2.5-5.25 V
- Operating Temperature:20~70 °C
- Material: Plastic.
- Application: Electronic Circuits.
The four spindles on the ICSH044A ICSTATION Blackberry Trackball Breakout Board 360 Degree Trajectory Ball Module Hall Effect Sensor have a tiny circular magnet the end; each of these is paired with an SMD hall effect sensor, which is used to measure up, down, left and right movements of the trackball.
The hall-effect sensors and trackball combo are surprisingly sensitive. A slight roll of the trackball creates multiple high/low transitions on the four axis pins, easily picked up by any microcontroller essentially giving you the option of adding a mouse to your project. A 360° rotation of the trackball, along with a single axis, will result in about 9 high/low transitions.
