This plastic adapter connects a micro servo to LEGO-compatible cross axle parts such as gears, wheels, and beams. Simply push the adapter's spline housing onto the shaft of a compatible micro servo, and the other end accepts a standard LEGO cross axle — bridging the gap between hobby servos and building-block mechanisms.

Key Features

  • Push-Fit Installation – No tools or adhesive required
  • 16 mm Length – Compact profile for small builds

Compatibility

  • Designed for micro servo splines only
  • Not compatible with standard-size servos or other spline types

Ideal For

  • Adding motorised movement to LEGO-compatible builds
  • Robotics projects combining servos with building-block structures
  • STEM education and creative prototyping

Package Contents

  • 1× Plastic Micro Servo Adapter (16 mm, LEGO cross axle)

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.
