Perfect for Arduino and Micro:bit projects, it also comes with dedicated customer support for any inquiries. ## Description Product description Feetech FS90R Servo 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. Wheel This black plastic wheel is press-fit onto the FS90R output gear shaft, and easy to make a nice drive solution for small robots. The wheels have silicone tires and measure 60 mm (2.36″) in diameter. Two additional mounting holes for 3-40 screws make it possible to use the wheel with several of mounting hubs. Size FS90R Servo Size: 23.2 × 12.5 × 22 mm Wheel Size: 56mm x 8mm Feature Compatible with Arduino This mini 360 degree servo with accessories is very cheap and is ideal for microcontroller systems like the BBC micro:bit, compatible with Arduino, Raspberry Pi, Robot RC Car Drones Smart Car and PICAXE. Speed or engine power is very convenient, no longer cumbersome to connect the remote control and receiver. It is equivalent to a "hand". Parameter Can be connected with two sets of steering wheel or electric adjustment; Single - chip control, good stability, high precision. Turn the knob to test the steering system. When the connection of the electronic controller (brush or no brush can be), you can get rid of the remote control equipment for manual speed control, for testing adjustment. The function of "moving receiver" simulates the rudder of the transmitter through the knob. 1. It is easy to detect and set the virtual, jitter and median of the server. 2. Servo Stall torque: 1.3kg.cm/18.09oz.in(4.8V), 1.5kg.cm/20.86oz.in(6V). 3.Operating speed is 110RPM (4.8V), 130RPM (6V), but you can change the pwm to change the servo speed , to make it slower or faster.

Review: Works great! - Took a moment to get the "tire" on the "wheel" but then the wheel mounted on the servo with no challenges at all, and was able to drive the servo with normal servo libraries on arduino very easily. Took a few moments to build a code wrapper around the Servo object. Remembering that 90 means stop, 180 means full speed forward, and 0 means full speed backwards was awkward. I have 2 new interfaces. One where 100 means full forward, and -100 means full backwards; and another where 1.0 means full forwards and -1.0 means full backwards (the latter just multiplies by 100 and uses the former). Anyway, lots of torque, lots of traction. Excellent for the small robots we're using. I'll come back and post a video when I have one. Review: Great Little Servos - Bought these for a science fair project. They are powerful for the size and quite sturdy. Arrived promptly and in perfect condition. Much easier to use than regular geared motors for mobile robots because no motor shield is necessary. ## Features - This feetech servo has CE & ROHS certificate.

No arduino.i plan to power them with a 5v regulated pdb.** A: Yes, you can. **Q: How accurate are these servos in terms of getting them to stop at a specific angle?** A: They are as precise as the standard micro servos. **Q: How do you get these servos to keep a zero? Mine keep being a little bit off zero in different directions every reboot** A: Manual adjustment: There is a potentiometer at the bottom of the servo, middle-point adjustment potentiometer **Q: What is the voltage limit for these? I'm not talking about the rated voltage. I need to know how much I can get out of these before they break.** A: Since they are PWM to vary speed, I am not sure why you would want to exceed the specifications. With a 5V PWM I once accidentally applied 9V on the DC supply line for a short duration < 1 minute and they survived. Why would you want to exceed the specification intentionally? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great! *by A***R on September 30, 2018* Took a moment to get the "tire" on the "wheel" but then the wheel mounted on the servo with no challenges at all, and was able to drive the servo with normal servo libraries on arduino very easily.

They are powerful for the size and quite sturdy. Arrived promptly and in perfect condition.

What a fluke. Edit -- I'm going to change to 4 stars, I ran some variable speed code through each one, and it seems like they all may work as expected, not sure why right out of the package one did not want to fully rotate like the others. They all seem good now, will be testing over the next few days and will update to 5 stars if they continue to be solid ## Frequently Bought Together - Geekstory Feetech FS90R 360 Degree Continuous Rotation Micro Servo Motor + RC Tire Wheel for Arduino Micro:bit (Pack of 4) - Miuzei MG90S 9G Micro Servo Motor Metal Geared Motor Kit for RC Car Robot Helicopter, Mini Servos for Arduino Project (10) - RC Digital Servo Tester 1 Channels Motor Servo Controller Centering Tool with Over-Current Protection & 2 Control Modes for RC Car Airplane Robots Tester Tool --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/70507468-feetech-fs90r-360-degree-continuous-rotation-micro-servo-motor-rc](https://www.desertcart.tn/products/70507468-feetech-fs90r-360-degree-continuous-rotation-micro-servo-motor-rc) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-06*
