DS04 360-degree Continuous Rotation Servo (38g, 5.5kg/cm, 4.8-6V)

The DS04-NFC is a standard-sized (micro) continuous rotation servo motor designed for precise speed and direction control. Unlike conventional servos that limit rotation to approximately 180°, this model rotates indefinitely in both directions, making it an ideal component for driving the wheels of mobile robots or autonomous platforms.

Speed and direction are controlled via PWM pulses (50 Hz): a pulse width of 1 ms causes maximum rotation in one direction, 2 ms in the other, while a 1.5 ms pulse stops the motor. An internal potentiometer allows precise calibration of the neutral point (complete stop) to ensure optimal stability when stationary.
