Continuous rotation servos are effectively servos without potentiometers to monitor their location. The have no end stops and will rotate continuously just like a normal gearmotor. The advantage to these over a normal gearmotor is the built in motor driver. Instead of moving to a specific point in their sweep based on the servo signal, these change speed. The further “left” or “right” the signal, the faster it will spin in that direction. The servo offers an inexpensive and easy to control method of getting your small turret spinning or miniature robot moving. This servo can work with both 5 V and 3.3 V servo signals and has a standard servo connector.
