Description: This is a tiny trackball akin to those found on a number of Blackberry models (8100, 8300, 8320, 8800, 8830, etc). Each of the four spindles have a tiny circular magnet on each end. Great when paired with very small SMD Hall effect sensors.
Ball is clear to allow for LEDs placed underneath to light up the ball.
