A compact 9g micro servo with metal gears, delivering 1.8 kgf·cm of torque at 4.8V. The metal gear train provides significantly better durability than plastic versions, especially in robotics applications where the servo is in near-constant motion.
With a 180° operating angle and a 320:1 reduction ratio, this servo is suited for small robots, automation tasks, and projects where space is limited but reliable torque is needed.

Jargon buster
Plain-language definitions for the technical terms used above.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
- Stall torque
- The maximum twisting force a servo can produce when its output is held still and cannot move. It helps you judge whether the servo is strong enough for a robot joint, steering linkage, or other load.
- Tolerance
- Tolerance tells you how far the real resistance value may be from the printed value. A 1% resistor is useful when a circuit needs more predictable behaviour than a looser 5% or 10% part.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
