The Parallax (Futaba) Continuous Rotation Servo is a high-quality servo motor specifically designed for robotics, automation, and basic motion control projects. Unlike standard servos that are limited to fixed angles, this model provides bidirectional continuous rotation, making it perfect for driving wheels, tracks, or other mechanisms that require smooth and precise movement.
Engineered for ease of integration, this servo works seamlessly with any Parallax microcontroller or PWM-capable device. Its linear response to PWM input allows you to control speed and direction effortlessly, from 0 to 50 RPM, enabling smooth ramping and precise control for your application.
Constructed with four secure mounting points and fully RoHS compliant, this servo is ideal for robotics enthusiasts, educational projects, and prototyping. It’s also very simple to program using PBASIC or SX/B PULSOUT commands, ensuring compatibility across a wide range of development environments.
⚠️ Important Note: Servo current draw can spike under load. Ensure your power supply and voltage regulator can deliver sufficient current for all connected servos. Do not power the servo directly from a BASIC Stamp module’s Vdd or Vin pins, and avoid connecting the servo’s Vss line directly to the BASIC Stamp module’s Vss pin.
