Review: Pedido incompleto. - Pedido incompleto. ## Features - Warning:Not suitable for children under 10 months. - Warning:Not suitable for children under 8 years. For use under adult supervision - 360° Continuous Rotation – FT90R digital servo provides full 360° continuous rotation (not limited to angle). Pulse width range 900‑2100μsec, neutral at 1500μsec. Speed and direction are fully controllable via PWM. - Digital Precision – Faster response and higher holding torque than analogue servos. Compact size (9g) with metal brush motor. Great for continuous rotation applications like robot wheels, tank tracks, and conveyor belts. - Wide Voltage & Easy Control – Operating voltage 4.8V–6V DC (works perfectly with 5V microcontrollers). Compatible with Arduino/micro:bit/Raspberry Pi, and any PWM output. - Versatile Applications – Ideal for RC robot steering, helicopter tail rotors, airplane throttle controls, boat rudders, and car steering. Also great for DIY projects like pan‑tilt mechanisms or multi‑servo robotic arms. - Complete 4‑Pack with Wheels – Includes 4x FT90R 360° servos + 4x plastic wheels (compatible with 20T spline). Each servo size: 22.9×12.1×26.5mm, weight 9g. Ready to build a 4‑wheel drive robot or replace worn‑out servos. ## Technical Specifications | Specification | Value | |---------------|-------| | Package Dimensions | 14.22 x 12.95 x 3.81 cm; 227 g | | Manufacturer recommended age | 13 years and up | | Item model number | ST3328X4+ST2913X4 | | Assembly Required | No | | Batteries Required? | No | | Batteries included? | No | | Material Type(s) | Plastic | | ASIN | B07JDSX47S | ## Images ![4 Pack FT90R 360° Continuous Rotation Digital Micro Servo (9g) with Wheels, for Arduino RC Robot, Helicopter, Airplane, Boat & Car Steering - Image 1](https://m.media-amazon.com/images/I/61C7E8nWNkL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice for a small wheeled robot *by L***N on 9 November 2022* I liked that the wheels were included for what some charge for just the servos. ### ⭐ Pedido incompleto. *by J***M on 19 December 2025* Pedido incompleto. ### ⭐ Funcionamiento calidad no adecuados. *by L***A on 4 May 2022* El producto no es compatible con el lenguaje de programación con el que estoy trabajando. --- ## 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.pl/products/440512051-4-pack-ft90r-360-continuous-rotation-digital-micro-servo-9g](https://www.desertcart.pl/products/440512051-4-pack-ft90r-360-continuous-rotation-digital-micro-servo-9g) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-06-04*
