Parallax (Futaba S148) Continuous Rotation Servo #900-00008

Parallax (Futaba S148) continuous rotation servo.

Overview

The Parallax (Futaba S148) continuous rotation servo converts standard RC servo position pulses into continuous rotation speed. It can be controlled directly by a microcontroller without any additional 3p男女做爰高潮了, which makes it a great actuator for robotics projects. The servo includes an adjustable potentiometer that can be used to center the servo and comes with a star-shaped servo horn and an 11″ (270 mm) lead.
