About this product
This 15 kg.cm metal gear servo motor rotates approximately 120 degrees and holds its shaft position as long as the control signal stays unchanged. It works with any standard servo code, hardware or library, which makes it suitable for beginners. Typical uses include robot arms, model aircraft control surfaces and any mechanism that needs a set angle.

Frequently asked questions
How do I wire the servo to an Arduino?
Typically the red wire is power, the brown or black wire is ground, and the yellow or orange wire is the signal, which goes to a PWM pin. At this torque the servo draws high current, so power it from an external supply that matches its rated voltage rather than the Arduino 5V pin.
Can this servo rotate a full 360 degrees?
No. It rotates approximately 120 degrees, so it is a standard positional servo and not a continuous-rotation servo.
