FEETECH FS0307 Sub-Micro Servo with a LEGO Minifigure as a size reference.


This is a great general-purpose actuator for tiny mechanisms. The FS0307 is a very small 4.4 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. (In our tests, we were able to get an expanded range of approximately 180° over a pulse range of 650 µs to 2500 µs, but as this is not part of FEETECH’s official specifications, it is possible different units will behave differently in this regard.)

The servo has a 6″ (15 cm) cable that is terminated with a standard JR-style connector, which is Futaba-compatible, and it includes additional servo horns and mounting hardware.

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

You can find more information about this servo in its datasheet (98k pdf).

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