Feetech FS90R Micro Continuous Rotation Servo

The Feetech FS90R Micro Continuous Rotation Servo is a compact and lightweight servo motor designed for applications that require continuous rotational movement instead of positional control.

Unlike standard servos that rotate to a specific angle, the FS90R operates using continuous rotation. The speed and direction are controlled using a PWM signal from a microcontroller such as Arduino, ESP32, or Raspberry Pi. A pulse around 1.5ms stops the servo, while higher or lower signals rotate the servo clockwise or counterclockwise.

Because of its small size and reliable performance, the FS90R is widely used in robot cars, drive mechanisms, automation systems, and STEM education projects where compact motorized movement is needed.

Perfect for makers looking to add simple and efficient motion control to robotics and electronics builds.
