FEETECH FS90 Micro Servo with a LEGO Minifigure as a size reference.

Overview

This is a great general-purpose actuator for tiny mechanisms. The FS90 is a 9 g analog servo from FEETECH (formerly known as Fitec) that offers position control over an approximate 120° operating angle for servo pulses between 900 µs and 2100 µs. As with most servos, the pulse range can be expanded to achieve an expanded operating angle, but the limits of this are not specified by FEETECH. The servo has a 8″ (200 mm) lead that is terminated with a standard JR-style connector, which is Futaba-compatible, and additional servo horns and mounting hardware are included.

The servo cable is terminated with a Futaba-compatible JR-style connector.

An example of hardware included with the FEETECH FS90 and FS90R micro servos. Actual hardware might vary.

You can find more information about this servo in its datasheet (69k pdf).

For more advanced robotics applications, please note that we also carry a version of this servo that is specially modified to provide access to the feedback potentiometer through a fourth (green) wire, which lets you monitor the actual position of the servo from your controller:

FEETECH FS90-FB Micro Servo with Position Feedback.

Note that as with most hobby servos, stalling or back-driving this servo can damage it.

FS90 vs FS90R

Two versions of this servo are available. This product is the FS90, which offers closed-loop position control over a limited range. Alternatively, the FS90R is specifically designed to be a continuous-rotation micro servo that offers open-loop speed control. The FS90 and FS90R have identical dimensions and use the same motor, so the FS90 will also work with our 60×8mm wheel for the FEETECH FS90R.
