The Parallax continuous rotation servo is a Futaba S148 servo that has been modified for continuous rotation. Since servos have their own integrated control circuitry, this unit gives you an easy way to get your robot moving. Key specs at 6 V: 50 RPM (no-load), 38 oz-in (2.7 kg-cm), 43 g
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 electronics, which makes it a great actuator for robotics projects. The servo includes an adjustable potentiometer that can be used to centre the servo and comes with a star-shaped servo horn and an 11″ (270 mm) lead.
This servo is compatible with our servo controllers and our servo wheels and sprockets.

Most standard radio control servos (and all RC servos we sell) have three wires, each a different colour. Usually, they are either black, red, and white, or they are brown, red, and orange/yellow:
Please check the specs for your servo to determine the proper power supply voltage, and please take care to plug the servo into your device in the proper orientation (plugging it in backwards could break the servo or your device).
