Feedback 360 Degree ‐ High Speed Continuous
Rotation Servo
PRODUCT ID: 3614
Description
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.

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
