The FS90R Mini 360 Degree Continuous Rotation Servo by Feetech is a compact, multi-purpose servo ideal for microcontroller systems such as BBC micro:bit, Arduino, Raspberry Pi, and PICAXE. Perfect for radio controlled models and small robotics projects, this servo offers continuous 360-degree rotation.

This continuous rotation servo operates differently than standard servos: it remains static at a 1.5ms pulse, with the ability to tweak this via an included trimmer. Pulses longer than 1.5ms cause forward rotation, while shorter pulses cause backward rotation.

The FS90R converts standard RC servo position pulses into continuous rotation speeds. The middle-point potentiometer allows adjustment of the rest point, enabling precise control. It comes with mounting screws and various control horns.
