The GWS S125 1/2T 2BB Sail Winch Servo is a unique servo that has a wider rotation range than typical hobby servos. It rotates 180° over the standard 1-2 ms servo pulse range output by many RC receivers (typical hobby servos turn 90° over this pulse range).
- What are the three wires coming out of my servo?
Most standard radio control servos (and all RC servos we sell) have three wires, each a different color. Usually, they are either black, red, and white, or they are brown, red, and orange/yellow:
- brown or black = ground (GND, battery negative terminal)
- red = servo power (Vservo, battery positive terminal)
- orange, yellow, white, or blue = servo control signal line
Please check the specs for your servo to determine the proper power supply voltage, and please take care to plug the servo into your device in the proper orientation (plugging it in backwards could break the servo or your device).
