Description

The MG90S is a compact, high-performance micro servo featuring durable metal gears for increased strength and longevity. Popular in robotics, RC models, and DIY electronics, it offers a significant upgrade over plastic-geared alternatives like the SG90.

Available in 90°, 180°, and 360° versions, the MG90S gives you flexibility depending on your control needs:

  • 90° and 180° Versions: Precise positional control for arms, linkages, and steering mechanisms.

  • 360° Version (Continuous Rotation): Ideal for drive wheels or winches. This version does not support angle positioning but responds to standard PWM signals for directional speed control.

For the 360° model:

  • 1500μs PWM = Stop

  • >1550μs = Clockwise rotation, speed increases up to 2000μs

  • <1450μs = Counterclockwise rotation, speed increases down to 1000μs

Metal gears ensure reliable operation under load, making the MG90S a trusted choice for demanding applications in a small form factor.
