An ultra-compact 2.5g micro servo with 360-degree continuous rotation, ideal for micro robots and space-constrained projects. The coreless motor and POM gears deliver smooth, reliable rotation in a tiny form factor measuring just 19.6 × 8.0 × 16.3mm.

Controlled via standard PWM servo signals, it connects directly to an Arduino output pin without a motor driver. Write 0° for full-speed clockwise, 90° to stop, and 180° for full-speed counterclockwise using the Arduino Servo library.
