SG90 9g Micro Plastic Gear Servo (180° Rotation)

Product Overview

SG90 9g Micro Plastic Gear Servo (180° Rotation)

The SG90 9g Micro Servo is an industry-standard, lightweight actuator engineered for indoor 3D foam flyers, micro RC planes, park flyers, robotics, and educational electronics. Combining a compact 9-gram chassis with high-toughness nylon gears, the SG90 offers smooth proportional movement, low operating noise, and a reliable stall torque of up to 1.8 kg.cm at 6.0V.

Low-Noise Nylon Gearing & Rapid Response

Equipped with precision-molded POM/nylon reduction gears and driven by a micro coreless motor, the SG90 maintains smooth engagement and ultra-low running chatter. Its optimized control board provides crisp signal response and accurate 180-degree angular travel, making it ideal for micro control surfaces and robotic arm joint control.

Universal Receiver & MCU Compatibility

Pre-wired with a 250mm flexible lead and a standard 3-pin JR connector, the SG90 is plug-and-play compatible with Spektrum, Futaba, FrSky, Flysky receivers, as well as standard microcontrollers (e.g., Arduino, Raspberry Pi, ESP32). Each servo is supplied in a complete set containing multiple plastic servo arms and mounting screws.

Key Advantages & Engineering Highlights

• 180° Wide Angular Deflection: Provides extended deflection angles required for micro flight surfaces and robotic linkages.
• Ultra-Lightweight Footprint: Weighs only 9 grams, keeping total airframe weight low for maximum thrust-to-weight performance.
• Strict Quality Assurance: Built under strict ISO 9001 production and testing guidelines for consistent reliability.
