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. Highlights: Continuous Rotation Servo: Provides 360° continuous rotation instead of positional control. PWM Speed & Direction Control: Rotation speed and direction are controlled using standard servo PWM signals. Compact Micro Size: Lightweight 9g servo ideal for small robotics projects. Wide Voltage Compatibility: Operates from 4.8-6V, compatible with most robotics power systems. Easy Microcontroller Integration: Works with Arduino, ESP boards, Raspberry Pi, and other development platforms. Specifications: Operating Voltage: 4.8-6V. Stall Torque: ~1.3kg cm @ 4.8V / ~1.5kg cm @ 6V. Operating Speed: ~100 RPM @ 4.8V / ~130 RPM @ 6V. Control Signal: PWM (standard servo signal). Rotation Type: Continuous 360°. Weight: ~9g.
