SG90 9G Micro Servo Motor 180 degree and 360 degree Options Key benefits Compact and lightweight 9g design fits tight spaces in small aircraft, robots, and hobby projects. Two rotation options let you match motion to the task: 180 degree for precise positioning, 360 degree for continuous rotation applications. Easy to integrate with common RC receivers and control systems, suitable for hobbyists and electronic starters building remote control models. Versatile use reduces the need for larger actuators, saving space and simplifying mechanical design. What it does and why you need it This micro servo provides reliable actuation for control surfaces, small joints, and drive mechanisms in radio controlled and robotic projects. The 180 degree version delivers controlled angular positioning for flaps, steering, and arm joints. The 360 degree version provides continuous rotation for small wheels, conveyor mechanisms, or simple drivetrain tasks. Both options offer a compact, lowmass solution where space and weight are limited. Features and attributes Model: SG90 Weight: 9g micro servo Rotation options: 180 degree positional or 360 degree continuous rotation Function: electronic starter micro servo for RC and robotics applications Compatibility: suitable for RC airplane, helicopter, remote control vehicles, robot arms, and general hobby electronics controlled by standard PWM servo signals Practical use scenarios Small robot arm joint: Use the 180 degree servo to control a shoulder or wrist joint for pick and place tasks in light duty setups. RC airplane or helicopter control surface: Install the 180 degree servo to operate flaps, rudder, or elevator with compact linkages. Wheeled micro robot drive: Choose the 360 degree continuous rotation servo to power small wheels or a simple differential drive for mobile robots. Notes Available in 180 degree and 360 degree variants; select the version that matches your motion requirements.
