4wd Robot chassis Steering wheel

The world’s most popular micro servo for hobbyists and students. Lightweight, affordable, and incredibly easy to control, the SG90 is the go-to choice for small-scale robotics, camera gimbals, and Arduino-based automation projects. Quality assured by Pro Tronix.

Product Overview

The SG90 Micro Servo from Pro Tronix is a tiny but mighty actuator that has become a staple in the maker community. Weighing only 9 grams, it packs enough punch to move small linkages, open latches, or rotate sensors.

Because it operates on a standard 180-degree rotation, you can precisely control its position to any angle between 0 and 180 degrees using PWM (Pulse Width Modulation). It is designed to work perfectly with the 5V output of an Arduino, ESP32, or Raspberry Pi, making it the ideal entry point for anyone learning about motion control and robotics.

Key Features

• Ultra-Lightweight: At just 9g, it is perfect for weight-sensitive projects like RC indoor flyers or small walking robots.

• Easy to Interface: Comes with a standard 3-pin connector (GND, VCC, Signal) that plugs directly into most sensor shields.

• Complete Accessory Kit: Includes 3 different servo horns (arms) and mounting screws to fit various mechanical setups.

• Great for Learning: The most supported servo motor in terms of online tutorials, libraries, and 3D-printable designs.

Common Applications

• Arduino Starter Projects: Learning how to control movement with sensors (e.g., a radar using an Ultrasonic sensor).

• DIY Camera Gimbals: Building a pan-and-tilt mount for small FPV or Pi cameras.

• Automatic Pet Feeders: Controlling a small trapdoor or rotating dispenser.

• Animated Props: Adding eye or limb movements to Halloween props and artistic installations.

💡 Wiring Tip:

• Brown Wire: Ground (GND)

• Red Wire: Positive (VCC 4.8V - 5V)

• Orange/Yellow Wire: Signal (PWM)
