A 3-pin 10cm cable designed for connecting servo units in robotic projects.

The FS90 is an analog micro servo that has 120° of rotation. The servo is ideal for the beginning roboticist and is perfect for use with the Motor Shield for Arduino. The servo can be controlled using any servo code, hardware or library and to control with an Arduino, simply connect the orange control wire to pin 9 or 10 and use the Servo library included with the Arduino IDE.

• Good for making simple moving robots
• Small dimensions means servo can fit in confined spaces
• Lightweight
• Operating voltage 4.8 to 6V
• A 3-pin 10cm cable is available for connecting servos (37-1337)

To connect an Arduino to a SCServo digital servo requires a TTLinker comtrol board. The TTLinker is a signal conversion board. Arduino needs to convert its UART signals to the half duplex type and through TTLinker connect to SCServo. The TTLinker also has more interfaces to make provision for more sensors.

When an Arduino is being used to control the SCServo an Arduino library is required, which can be downloaded here.

Note: There may be some compatibility issues with Windows 10.
