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
- A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- 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.
