Analog 360° Continuous Rotation 9g Servo (FS90R)

The Analog 360° Continuous Rotation Servo (FS90R) is a micro-sized servo that has been built specifically for continuous rotation. At 6 V, it has a maximum rotation speed of around 100 RPM (no-load) and can produce up to 20.86 oz-in (1.5 kg-cm) of torque. It can be controlled to rotate in clockwise or counterclockwise directions with given rotation speeds. Also, there is a built-in potentiometer to adjust the stopping point of the servo motor.
