The FS90R is a special servo made for continuous rotation. It can make full revolutions forward or backward, which makes it great for projects such as driving wheels on a small robot.
The FS90R servo includes an adjustment potentiometer to calibrate the middle-point (stopped) setting. Calibrate this setting by sending a 1.5ms (1500µs) pulse signal (position "90" when used with the Arduino Servo library), then slowly turn the middle-point adjustment potentiometer until the servo stops rotating. Access the middle-point adjustment potentiometer by inserting a small screwdriver into the hole in the bottom of the servo, see diagram below.
The servo's cable has a standard JR-style connector on the end.
