With a 180-degree rotation, quick response time of 0.12 seconds at 4.8V, and a versatile 3-wire connection, this servo motor is perfect for various applications, including robot arms and automated systems. Each package includes four motors, servo arms, and screws, making it easy to kickstart your next project. ## Description What is SG 90 servo? It is tiny and lightweight with high output power. This servo can rotate approximately 180 degrees (90 in each direction) and works just like the standard kinds but smaller. You can use any servo code, hardware or library to control these servos. It comes with 3 horns (arms) and hardware. A Servo can be positioned to specific angular positions by sending the servo a coded signal. Servos, in general, require a lot of currents to operate since they have a motor inside. If you only need to control one small servo like this one you can connect it directly to Arduino. If you need to control two or more servos you need an external power supply or battery pack. Specifications Operating voltage: 4.8 V ~6V Operating speed: 0.1 s/60 degree Stall torque: 1.8 kgf·cm Dead bandwidth: 10 µs Temperature range: 0 ºC – 55 ºC Weight: 9g How to connect SG90 micro servo motor to Arduino Uno? The connection with Arduino is extremely easy. The servo has three leads. The brown one is the Ground so connect to it Arduino Ground. The red one is VCC which usually requires a voltage between four points eight to seven point two volts. So connect it to Arduino 5V. The last lead, the orange one is the control signal which needs to be a PWM signal with a periodic time of twenty milliseconds aka 50 Hertz and a duty cycle of one to two milliseconds so five to ten percent. While an on time of one millisecond represents the -90° position of the motor shafts, one point five milliseconds represent 0° position and two milliseconds the plus 90° position. That means you can rotate the shaft a total of 180°. The SG90 servo has 3 wire interfaces in which the connections should be made as follows: Red wire-5V Brown wire-Ground Yellow wire-digital pin 9 ## Features - 【Small Size】It is tiny and lightweight with high output power.

MakerDoIt Customer Service Team **Q: Can this be controlled by a raspberry pi?** A: Yes **Q: Can these be used for rc plane control surfaces (rudder and stabilizer) of a hobbyzone mini super cub brushless conversion)?** A: Yes **Q: does it have 4 servos or one with 4 peaces?** A: Hello, it has 4 servo motor. ## Customer Reviews ### ⭐⭐⭐⭐ 4.0 out of 5 stars Software is key *by R***N on Reviewed in the United States on January 2, 2020* Found that servos were nicely packaged, received in good working shape.Seeking out good software that allows me to operate servos working at same time using Arduino.Suspect PWM is constricting usage at same time.Would be helpful if supplier had helpful hints for making software work with multiple unist at same time. Why I rated four stars.Accessories with servos were fine and worked well. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Surprised *by D***W on Reviewed in the United States on March 1, 2021* They work great and for a awesome price. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works as expected *by J***O on Reviewed in the United States on March 28, 2021* Servo performs as expected. --- ## 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.kg/products/70179824-makerdoit-4pcs-micro-servo-motor-sg90-for-robot-arm-hand](https://www.desertcart.kg/products/70179824-makerdoit-4pcs-micro-servo-motor-sg90-for-robot-arm-hand) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-18*
