Servo Motor SG90 (360 Degree Rotation) OverviewThe Servo Motor SG90 (360 Degree Rotation) is a compact and versatile continuous-rotation servo designed for robotics, automation and hobbyist applications. Combining small size, low weight and PWM-based control, the SG90 is a popular choice for beginners and advanced makers who need reliable rotational motion with simple integration.Key Features360-degree continuous rotation: Full rotation capability for driving wheels, turntables and conveyor elements.Compact and lightweight: Approximately 9g and a small footprint for space-constrained designs.Durable build quality: Constructed with reliable materials for long service life in hobby and educational projects.Easy PWM control: Controlled via standard PWM signal, compatible with Arduino, Raspberry Pi and most microcontrollers.Low power draw: Efficient operation within 4.8V to 6V suitable for battery-powered systems.SpecificationsOperating Voltage: 4.8V – 6VTorque: Up to 1.8 kg/cm (at 6V)Speed: 0.12 sec/60° (at 6V)Weight: Approximately 9gDimensions: 22.2mm x 11.8mm x 31mmSignal Type: PWM controlRotation: 360-degree continuousWiring and ControlThe SG90 uses standard three-wire connections: power (VCC), ground (GND) and signal (PWM). It accepts PWM control pulses from microcontrollers such as Arduino and Raspberry Pi. Typical integration suggestions:Use a stable 4.8V to 6V supply rated for your number of servos to avoid voltage drops.Connect signal to a PWM-capable GPIO pin and use the appropriate library (Servo library on Arduino) to generate control pulses.For multi-servo systems, use an external power source or servo driver to prevent brownouts on your microcontroller.Common ApplicationsWheeled robots and smart cars for continuous wheel drivePan-tilt camera mounts and surveillance rigsDIY robotics projects and educational STEM kitsConveyor and small automation mechanismsPrototyping and hobbyist automationPackage Contents1 x Servo Motor SG90 (360 Degree Rotation)3 x Assorted servo horns with screwsTips for Best PerformanceCalibrate your controller code to set appropriate neutral and speed values for continuous rotation servos.Avoid prolonged stall conditions to prevent overheating and reduce wear.If you need precise positional control instead of continuous rotation, use a standard positional SG90 variant.Secure mounting and proper servo horns will improve torque transfer and reduce mechanical play.Note: Images are for illustration purposes only.
