FS90R continuous Rotation Micro Servo (1.5 kg.cm) FeeTECH

From the shop's description

This is a high quality continuous rotation servo. This servo rotates can rotate continuous to forward direction or backward direction and allow the control of rotation speed and also the change of direction. It can be controlled using Arduino or micro-controller. Features ​ Continuous rotation Operating voltage: 4.8-6.0VDC Top operating speed: 60-70RPM (4.8-6.0VDC respectively) Torque: 1.2-1.5 kg-cm (4.8-6.0VDC respectively) Important Notes on How to Use 1- With Regular servos, you can control the angle and direction of rotation where the motor stop at. The angle of rotation is usually limited by 90 degree clock/anti-clock. 2- While continuous rotation servos we control speed and direction of rotation and the rotation angle is not limited of course. 3- Similar to regular servos, continuous rotation servos are controlled by pulse width which can be easily generated by Arduino either using hardware or Arduino servo library (click here for more details). 5- The servo have 3 wires: ground, power and control signal. 6- As was the case with regular servos, the same PWM settings are used but in this case .9-1ms pulses = fast one direction, 1.5ms = stopped , 2-2.1ms = fast the other direction. 7- Good for making simple moving robots and application that require speed and direction control.
