One is making a pan-tilt camera holder, and the other is a 4WD robot. This item was exactly what I needed.I hooked them up to a PCA9685 I2C Servo Shield, and connected that to an NodeMCU. I secured the servos with wrenches (so they wouldn't fay off my table). You can see the continuous rotation counterclockwise and clockwise.If you are looking for continuous mode servos (you can use them in the old school 180 degree fashion), look no further. ### ⭐⭐⭐⭐⭐ Nice for a small wheeled robot *by L***N on Reviewed in the United States on 9 November 2022* I liked that the wheels were included for what some charge for just the servos. --- ## 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.tw/products/440512051-4-sets-mini-9g-digital-servo-ft90r-360-degree-continuous](https://www.desertcart.tw/products/440512051-4-sets-mini-9g-digital-servo-ft90r-360-degree-continuous) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-05-19*
