Parallax Feedback 360° High-Speed Servo

The Parallax Feedback 360° provides the functionality of a light-duty standard servo, a continuous rotation servo, a high-speed servo, and encoder feedback in one convenient package. Its speed is controlled with standard RC servo pulses, just like a typical continuous rotation servo, and it provides a return signal line from an internal Hall effect sensor that provides digital angular position feedback. An external microcontroller can use this signal to make the servo hold any angle, much like a standard servo except without any limits on the range of motion, or it can use it for closed-loop speed control. Recommended operating voltage range is 5.8 V to 8.4 V

Key specs at 6 V: 140 RPM (no-load), 35 oz-in (2.5 kg-cm), 41 g, CCW rotation for pulse widths above the rest point.
