The MG90S Micro Servo Motor (360° Continuous Rotation) is a compact, hobby-friendly analog RC servomotor designed for robotics, RC models, and DIY automation projects that need controlled continuous spinning in a small footprint. This version is continuous rotation, meaning it behaves like a tiny geared motor driven by a standard servo PWM signal—ideal for robot wheels, rotating platforms, feeders, mini conveyors, and lightweight drive mechanisms.
Unlike positional servos (that move to a fixed angle), a continuous rotation servo uses PWM to control rotation direction and speed:
This makes it very easy to control using common servo libraries on Arduino/ESP32 and RC receivers.
Typical wiring colors:
Servos can draw higher current during startup, load changes, or stalls. For best results:
