MG90S - Tower Pro Metal Gear Servo Specifications

Nov 2, 2026

The MG90S is a high-performance, lightweight micro-servo equipped with durable metal gears, specifically designed for compact applications in robotics, RC airplanes, helicopters, and quadcopters. This document details its technical specifications, including a weight of 13.4 grams, dimensions of 22.5 x 12 x 35.5 mm, and variable stall torque ranging from 1.8 to 2.2 kgf·cm. It operates within a voltage range of 4.8V to 6.0V, utilizing pulse width modulation (PWM) with a 20ms period to achieve 180-degree rotation. The servo provides precise positioning control through a 1ms to 2ms pulse duty cycle, making it an ideal, user-friendly choice for beginners integrating motorized movement into small-scale electronic projects without requiring complex external feedback-driven controllers.
