MG90S is a 9 g micro servo motor with metal gears, designed for precise angle control in small robots, RC models, and Arduino projects. It is compact, lightweight, and easy to drive with standard PWM signals.
Product description
Type: 9 g micro servo motor with internal metal gear train for higher durability and torque.
Control signal: Standard PWM, using a 3‑wire connection (signal, VCC, GND).
Operating angle: Up to about 180° of rotation, controlled by pulse width.
Signal range: Typically responds to pulses from about 1 ms (one end) to 2 ms (other end), with around 1.5 ms at the center position.
Voltage: Designed to run from about 4.8 V to 6.0 V, making it suitable for common 5 V systems like Arduino.
Torque: Roughly in the 1–2 kg·cm range (higher torque at 6.0 V than at 4.8 V).
Speed: Moves about 60° in around 0.1–0.2 seconds depending on voltage and load.
Size and weight: Typical dimensions are around 22.5 × 11.5 × 27 mm, with a weight close to 13–14 g, so it fits well in tight or lightweight builds.
Typical use: Ideal for steering mechanisms, small robot joints, sensor panning/tilting, and other angle-control tasks for beginner and first‑year engineering projects.
Note: Product size and dimensions may vary slightly between batches or manufacturers.
