MG90S Metal Gear Servo Motor (180 Degree Rotation)

Servo Motor MG90S — High-Torque 180° Micro ServoThe Servo Motor MG90S is a compact, high-performance micro servo designed for precise angular control in hobbyist, educational, and light industrial applications. With metal gear construction, a wide operating voltage range, and fast response times, the MG90S delivers dependable motion control for robotics, RC vehicles, camera gimbals and more.Why Choose the MG90S Servo?Durable Metal Gears: Metal gear train improves longevity and withstands higher loads than plastic-geared alternatives.High Torque in a Small Package: Delivers up to 2.2 kg·cm torque at 6V while remaining lightweight and compact.Accurate Positioning: Smooth control with an angular resolution around 2–3° for reliable repeatable movements.Fast Response: Quick actuation helps with responsive steering, arm movements, and camera stabilization.Budget-Friendly: Excellent value for makers, students, and professionals needing cost-effective motion control.Key FeaturesRotation angle: 180° (standard micro servo sweep)Operating voltage: 4.8V – 6V (compatible with common battery packs and regulated supplies)Torque: 2.0 kg·cm @4.8V; 2.2 kg·cm @6VSpeed: 0.10 s/60° @4.8V; 0.08 s/60° @6VConstruction: Metal gear train for improved durabilityDimensions: 22.8 mm × 12.2 mm × 28.5 mmWeight: 13 gTechnical SpecificationsModel: MG90SRotation: 180°Operating Voltage: 4.8–6VTorque: 2.0 kg·cm (4.8V), 2.2 kg·cm (6V)Speed: 0.10 s/60° (4.8V), 0.08 s/60° (6V)Dimensions: 22.8 × 12.2 × 28.5 mmWeight: 13 gTypical ApplicationsRobotic arms, grippers and legsRC vehicles — steering and control surfaces (cars, planes, boats)Camera gimbals and stabilization systemsEducational projects and STEM kitsPrototype mechanisms and small automation tasksInstallation & Wiring TipsPower: Use a stable 4.8–6V supply. For multiple servos, supply a dedicated regulated source to avoid brownouts.Signal: Standard PWM control; typical frequency ~50 Hz. Pulse width ~1–2 ms maps servo position across its 180° range.Grounding: Connect servo ground to your controller ground to ensure reliable signal reference.Mounting: Use available mounting tabs or custom brackets. Avoid over-tightening screws to prevent gear or case stress.CompatibilityThe MG90S works with most microcontrollers and flight controllers that output standard PWM servo signals, including Arduino, Raspberry Pi (with PWM driver), STM32, Pixhawk, and popular RC receivers.Tips for Best PerformanceRun at 6V when you need maximum torque and fastest response, but confirm servo hardware and system tolerances before increasing voltage.Limit stall time under heavy loads and consider a larger servo for sustained high-torque tasks.Periodically check servo horn screws and mounting hardware for tightness and wear.What’s in the BoxMG90S Servo motor (1x)Assorted servo horns and mounting screwsDocumentation / wiring guideFinal NotesThe Servo Motor MG90S blends compact size, metal-gear durability, and precision control into an affordable package — a go-to choice for hobbyists, educators, and light-duty professional applications.
