|Parallax (Futaba S148) continuous rotation servo.|
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 center the servo and comes with a star-shaped servo horn and an 11″ (270 mm) lead.
- Power: 4.8 – 6 V
- Top 6 V speed: 50 RPM (with no load)
