The Sheen Robotics 4000-0025-0002 is a descendant of the popular 4000-0025-0001 servo. The 25-2 received some noteworthy updates including an ultra stout steel gear train, more torque and a new top case. Like its predecessor, the 25-2 boasts two different modes which allow it to fill a variety of roles on your robot or project. In the default mode, the servo is able to rotate 300 degrees while having positioning feedback. In this mode, the PWM signal will determine the position of the servo. Using the 3102 Series Dual Mode Servo Programmer (1-1) the servo can be toggled into continuous rotation mode. In this mode, the servo will have proportional speed control based on the PWM signal that you send with your servo controller.
