## Overview

The 4Pcs SG90 9g Micro Servos deliver high-speed, precise 180° rotation with a stall torque of 1.8kg/cm, operating efficiently within a 4.8-6V range. Their compact 9g design and nylon gears make them ideal for a wide range of RC applications including helicopters, airplanes, cars, boats, and robotic arms. Easy to integrate with Arduino and other controllers, these servos combine performance and versatility for makers and hobbyists aiming to elevate their projects.

## Description

This kind of micro servos can be used for helicopter, airplane, car and boat. It owns high quality and high cost performance. In the meanwhile, it is light weight and has a small size. I believe it is a good tool for you. Specification: Model: SG90 Weight: 9g Stall torque: 1.8kg/cm Operating speed: 0.1sec/60degree Operating voltage: 4.8V Temperature range: 0℃ ~ +55℃ Dead band width: 10us Maximum rotation angle: 180 degrees Gear medium: nylon Working mode: Simulation Circuit connection: Yellow line (signal line) Red line (power line) Brown (ground) Package includes: 4* SG90 9g Micro Servos 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°.

Review: Good customer service; helped me in a pinch. make sure you use 5v power as 3.3v is too low for these models, I guess.
Review: Good servos. For the makers amongst us, the servo spline is 21 teeth at .25 modulus that you can make in fusion and print with a resin printer

### ⭐⭐⭐⭐⭐ Review
*by T***N on 10 November 2023*

At 50Hz a pulse width of 0.5ms corresponds to (0 deg) and a pulse width of 2.5ms corresponds to (180 deg). So a 2.5% duty cycle to 12.5% duty cycle is the range. The photo depicts 1ms(0 deg) to 4ms(180 deg) as the range which is not correct. All 4 worked normally and were able to traverse 0 to 180 degrees. They are not high end servos but for the price they work fine.
