Analog Micro Servo
Continuous Rotation
The FS90R is an analog micro servo that is capable of continuous
rotation clockwise or anti-clockwise, as opposed to moving to a
set position. 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, just connect the orange control wire to pin
9 or 10 and use the Servo library included with the Arduino IDE.
Also available is a wheel (37-1338) that can be attached directly
to the servo. The servo and wheel are also available as a package
(37-1336).
• 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)
