Tower Pro SG90 Continuous Rotation 360 Degree Servo

This TowerPro SG90 Continuous Rotation 360 Degree Servo Motor is special among all the available servo motors because its operation is very different from that of a standard servo. As instead of going to a specified angle, this servo will be static at a 1.5ms pulse, a longer pulse gives forward rotation and a shorter pulse give backward rotation.
