38g S3003 Standard Servo

The 38g S3003 Standard Servo is a standard-size analog servo motor designed for RC models, robotics, mechanical mechanisms, and other applications requiring controlled rotational movement. It operates on a 4.8V–6V supply and provides up to 4.1 kg·cm of torque at 6V, with a speed of approximately 0.19 seconds per 60° at 6V. The servo offers a 180° rotation range and uses a plastic gear mechanism, making it suitable for applications where a standard-size servo is required. Its approximately 38g weight and 40 × 20 × 38mm dimensions make it suitable for RC cars, boats, aircraft models, robots, mechanical arms, and similar projects. The servo uses PWM control and a three-wire connection for power and signal. Before installation, verify the operating voltage, mounting dimensions, connector configuration, torque requirements, and available space of your application to ensure compatibility.
