FS90R micro servo manufactured by FEETECH for continous rotation, ofering a cheap and easy way to control the wheel speed of a robot. Wheels with dimmensions 60x8mm can be specifically used for this servo.
The servo can be controlled with a microcontroler, such Arduino, without requiring additional electronics. The FS90R accepts a standard RC signal which corresponds to a 1.5m pulse width (equivalent to 90º of a position servo) to keep the motor stopped.
