When a servo is operated under complex circumstances such as robot and model, it may get stuck, burned or damaged due to external forces, which could bother you a lot... Now DFRobot is launching a series of servos with a clutch function and electronic protection that can solve your problems perfectly. Clutch Function When the angle of a servo is changed by external forces during normal operation, the servo can automatically reset and continue working through the clutch function, which prevents it from being damaged. Electronic Protection After being blocked for 5 seconds, the servo will automatically turn off its power to avoid getting burned. Servo Internal Structure This servo features large torque, stable performance, accurate running angle, and is easy to install. The operating voltage is 4.8~6V. When the servo is powered at 6V, its stall torque will exceed 1.2 kg. There are no limited switches inside the servo so it can rotate smoothly at 180 degrees (manually only). Meanwhile, the servo could operate fluently with minimal power, and you can just supply power to it by a normal battery or USB. In addition, users can directly control the servo using servo libraries in Arduino IDE and let it reach a maximum 180 degrees rotation angle within the pulse range of 500-2500μsec.
