The SG90 Plastic Gear Servo Motor is an low cost servo in a compact package. It is commonly used in light-weight radio controlled planes, helicopters, drones and robotics.

This is the perfect servo motor to use in microcontroller mechatronic projects where limited space is available, there isn't a need for large amounts of torque and servo accuracy is required.

Features of the SG90SR 180 Micro Servo:

  • 180 degree rotation
  • It can lift up to 1.5kg of weight positioned 1cm from the center of the shaft
  • Small size
  • Every motor is inspected and the basic operation verified


Package includes:

  • 1 - SG90SR Servo motor with attached 250mm control cable
  • 3 - arms/horns for various interface applications
  • Screws for mounting arms to the servo and mounting the servo to your project


Motor Connections:

The attached cable has a 3-pin female connector that is mated with a standard 0.1″ male header.
