Harder, better, faster, stronger! All the control and customization for your robot project. The Parallax Feedback 360° High Speed Servo has the functionality of a light-duty servo, continuous rotation servo, high-speed servo, and encoder in one convenient package - what a triple threat!
Like most continuous rotation servos, this is controlled by a standard 50 Hz pulse-width-modulation signal. But it adds a little extra - a feedback wire. This wire connects to an internal Hall effect sensor that will give you the absolute location/rotation of the horn. This feedback makes it easy to create projects where you want to turn and hold any angle with an unlimited range of motion! Or, rotate the servo continuously at a controlled speed—up to 120 RPM—as a robot drive motor.
Works great with the Motor Shield for Arduino, Servo/PWM HAT for Raspberry Pi, or our 16-channel Servo Driver, or by wiring up with the Servo Arduino library or CircuitPython code. Just about every microcontroller platform has support for analog Servo driving.
Features
- Bidirectional, continuous, feedback-controllable rotation from -120 to 120 RPM
- PWM positional feedback across entire angular range
- Internal Hall effect position sensor, which is not subject to wear or sensor deadband as are potentiometer-style feedback systems
- No need to manually “center” the servo
- 3-pin ground-power-signal cable plugs onto standard 0.1" 3-pin headers used for servos
- Separate single wire with female connector supplies feedback to a separate I/O pin
Jargon buster
Plain-language definitions for the technical terms used above.
- CircuitPython
- A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
- encoder
- An encoder is a sensor that converts the rotation or position of a shaft, knob or dial into electrical signals, reporting movement as incremental steps and direction, or as an absolute position. It is used to track how far something has turned, which matters for precise positioning, speed control, repeatable movement, or using a rotary knob as an input.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- potentiometer
- A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
