Description
The MG90S Metal Gear Micro Servo is a compact, high-torque servo designed for robotics, RC planes, model vehicles, and Arduino projects. With its durable metal gear train, fast response, and smooth 180° rotation, it offers improved strength and longevity compared to plastic-gear servo models like the SG90.
Perfect for small robots, pan-tilt systems, RC models, and precision mechatronics projects.
