MG90S Metal Gear Continuous Rotation Servo 360 Degree

This is the continuous-rotation modification of the standard MG90S - rather than holding a fixed angle, its internal feedback has been removed or disabled so it spins freely and continuously in either direction, controlled by the same PWM signal a positional servo uses but interpreted as speed and direction instead of target angle. That makes it genuinely useful anywhere a build wants a small, simple geared motor with built-in PWM control rather than needing a separate motor driver circuit.

The full metal gear train carries over from the standard MG90S, giving it the same durability advantage over plastic-gear alternatives, and a 25cm wire length gives more routing flexibility than the shorter leads found on positional servos typically mounted right at the control point. Included mounting horns (single, double, and four-point configurations) cover a range of attachment needs without sourcing hardware separately.

Common uses are small pan mechanisms and camera turrets needing continuous rotation rather than fixed positioning, small robot wheel drives wanting integrated PWM speed control without a separate motor driver, and compact mechanisms needing simple, continuous geared rotation.
