SG90 360° Continuous Rotation Micro Servo
120.00 EGP
A specialized version of the classic SG90, designed for infinite 360-degree rotation. Unlike standard servos that move to a specific angle, this “Continuous Rotation” motor acts as a miniature gear motor with controllable speed and direction, making it perfect for small wheeled robots. Quality assured by Pro Tronix.

Product Overview
The SG90-360 from Pro Tronix offers a unique twist on the standard micro servo. While it shares the same compact 9g footprint and 3-pin interface as the original SG90, the internal physical limits and potentiometer feedback have been modified.
Instead of moving to a specific angle (like 45° or 90°), sending a PWM signal to this servo controls its direction and speed of rotation. This makes it an incredibly simple and cost-effective way to drive the wheels of a mini-robot without needing a separate H-bridge motor driver. It is the ideal choice for small “line follower” robots, rolling toys, and rotating display stands.

-
Compact & Lightweight: The small 9g size is perfect for weight-sensitive mobile robots and tabletop gadgets.
-
Standard Mounting: Compatible with all standard SG90 3D-printable wheels and mounting brackets.
Common Applications
-
Miniature Wheeled Robots: Creating small, 2-wheel drive autonomous robots or line followers.
-
Rotating Displays: Powering slow-turning platforms for jewelry or product photography.
-
Winding Mechanisms: Useful for small pulley systems or automatic curtain/blind prototypes.
-
Art Installations: Adding continuous spinning motion to kinetic sculptures.
💡 Programming Tip: > Using the Arduino
Servolibrary:
write(90)usually stops the motor.
write(180)rotates it at full speed in one direction.
write(0)rotates it at full speed in the opposite direction.(Values near 90 can be used to fine-tune the “stop” point if the motor creeps.)

MG996R High Torque Metal Gear Servo
SG90 Micro Servo Motor | 180° Rotation
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.
