Smraza SG90 9G Micro Servo Kit (Metal Gear) – 10 Pcs for Arduino RC

Meet the Smraza SG90 9G Metal Gear Micro Servo Kit

The Smraza SG90 9G Metal Gear Micro Servo Kit brings compact, reliable motion to your Arduino, Raspberry Pi, or RC projects. Built with durable metal gears, this kit is designed to endure typical micro-scale tasks, from tiny robot arms to miniature aircraft controls. It’s a practical option for makers who value precise control in tight spaces without sacrificing build quality.

Engineered for enthusiastic hobbyists and students, the SG90 kit blends compact form with enough torque to handle small actuations. The result is a versatile motion component that fits neatly into crowded enclosures and learning setups while offering predictable, repeatable response patterns as you prototype and refine your ideas.

Key benefits and specs at a glance

• Metal gear construction resists tooth wear and heat deformation, helping the servos stay reliable under repeated micro-scale use.
• Fast micro-motion: approximately 0.08 seconds per 60 degrees, with a stall torque near 1.9 kg/cm across a full 180° range.
• Operating voltage: 4.8–6.0 V, compatible with common microcontrollers and compact power sources.
• Improved dead band of about 5 microseconds for crisper, more repeatable positioning in precise tasks.
• Includes servo arms and 24.5 mm leads to keep wiring neat in crowded DIY and RC builds.

Why metal gears matter

Metal gears tend to resist gear tooth wear and heat buildup better than plastic equivalents. For mini projects that see frequent actuation, this can translate to longer service life and steadier performance, especially under repeated cycles or modest loads.

Compatibility and integration

These SG90 servos are Arduino/Raspberry Pi ready and connect via a simple 3-pin PWM hookup compatible with JR/FUTABA receivers. The kit includes servo arms and 24.5 mm leads to help keep wiring tidy in tight spaces, making it easier to wire up prototypes and experiments.

Suggested use cases

• Micro-robotic projects needing precise, compact actuation for fingers, grippers, or tilt mechanisms.
• RC models such as fixed-wing planes, gliders, boats, or small helicopters where space is limited.
• Robotic arms or fixture systems in compact enclosures where reliable motion matters.
• Educational experiments with Arduino or Raspberry Pi that teach PWM control and mechanical motion.

Setup tips and notes

Note the requirement for a continuous PWM signal and a power supply capable of more than 1 A starting current. This helps ensure smooth startup and consistent performance during operation.
