The FS90R is a micro servo that has been built by FEETECH (formerly known as Fitec) specifically for continuous rotation, offering an inexpensive and easy way to get your miniature robot moving or small turret spinning. 

Key specs at 6 V: 130 RPM (no-load), 21 oz-in (1.5 kg-cm), 9 g


The FS90R is a micro-sized servo that has been built by FEETECH (formerly known as Fitec) specifically for continuous rotation. At 6 V, it has a maximum rotation speed of around 130 RPM (no-load) and can produce up to 21 oz-in (1.5 kg-cm) of torque. The servo can be controlled using a direct connection to a single microcontroller I/O line without any additional electronics, which makes it a great miniature actuator for beginner robotics projects.

The FS90R continuous rotation servo converts standard RC servo position pulses into continuous rotation speed. The default rest point is 1.5 ms, but this can be adjusted by using a small screwdriver to turn the middle-point adjustment potentiometer. Pulse widths above the rest point result in counterclockwise rotation, with speed increasing as the pulse width increases; pulse widths below the rest point result in clockwise rotation, with speed increasing as the pulse width decreases.

The servo has a 7″ (180 mm) lead that is terminated with a JR-style connector and includes additional servo horns and mounting hardware. The following picture shows an example of the hardware that might be included (actual hardware could vary):



This robotics servo, which is a continuous rotation version of the FEETECH (Fitec) FS90, is compatible with our servo controllers. If you are looking for a similar servo that is capable of limited-range position control as opposed to continuous rotation speed control, consider the Power HD micro servo HD-1900A, which has almost the same weight, speed, and torque as the FS90R.

Note: As of December 3, 2014, we are shipping V2.0 of this servo, which widens the deadband from ±5 μs to ±45 μs to make it easier to set a stationary neutral position. Also, the middle-point adjustment potentiometer has been changed to a lighter SMD potentiometer on the new version. The physical dimensions of the servo have not changed.

Hola Gonzalo, aunque el motor puede funcionar con 3,3V (reduciendo su velocidad), el circuito de control interno está preparado para recibir 5V por lo que no va a funcionar. Podes solucionar esto usando un transistor y una fuente de 5v. Saludos!

Hola, me pregunto si utilizando un Spark (Particle) Core, que trabaja a 3.3v, funcionaría a menor potencia o directamente no va a funcionar. Saludos.

Hola Rodrigo, este es el modelo FS90R, muy similar al SG90 pero no es el mismo. Saludos!

Este es el modelo Sg90? Saludos.
