Its output shaft is equipped with two ball bearings to reduce friction. The servo is compatible with standard RC servo pulses, delivering an operating angle of around 180° within a servo pulse range of 600 µs to 2400 µs. Additionally, it comes with a 12" (30 cm) cable that features a standard [JR-style connector](https://core-electronics.com.au/jr-connector-pack-female.html) that is Futaba-compatible. For more detailed information about the servo, please refer to its [datasheet](https://core-electronics.com.au/attachments/localcontent/FS5103B-specs_13293e22e07.pdf) (133k pdf). | \| [![](https://core-electronics.com.au/attachments/localcontent/0J7699_1400727d771.jpg)](https://core-electronics.com.au/attachments/localcontent/0J7699_12106677ddb.jpg) \| \|---\| \| The servo cable is terminated with a Futaba-compatible JR-style connector. \| | \| [![](https://core-electronics.com.au/attachments/localcontent/0J8211_2339278447c.jpg)](https://core-electronics.com.au/attachments/localcontent/0J8211_1037323c4ff.jpg) \| \|---\|---\| \| FEETECH Standard Servo FS5103B with included hardware (actual hardware might vary). \| | |---| This servo is also compatible with Pololu's [Mounting Bracket for Standard-Size Servos](https://core-electronics.com.au/mounting-bracket-for-standard-size-servos.html): | [![](https://core-electronics.com.au/attachments/localcontent/0J9430_199093972af.jpg)](https://core-electronics.com.au/attachments/localcontent/0J9430_5358682e364.jpg) | |---| If you're planning to use this servo in more advanced robotics applications, it's worth mentioning that Pololu offers a [modified version](https://core-electronics.com.au/feetech-standard-servo-fs5103b-fb-with-position-feedback.html) that includes a fourth (green) wire. This modification allows you to access the feedback potentiometer and monitor the servo's actual position from your controller, providing greater control and precision. | [![](https://core-electronics.com.au/attachments/localcontent/0J9679_26949d747fb.jpg)](https://core-electronics.com.au/attachments/localcontent/0J9679_283754b8ba4.jpg) | |---| | FEETECH Standard Servo FS5103B-FB with Position Feedback. | Note that, as with most hobby servos, stalling or back-driving this servo can damage it. **Comparison to the Power HD 3001HB servo** If you're looking for a budget-friendly option, the FS5103B servo is a great alternative to the Power HD [3001HB](https://core-electronics.com.au/power-hd-standard-servo-3001hb.html). With similar dimensions and performance, these two servos are generally interchangeable for most applications.
