Description
The Tower Pro SG90 Micro Servo Motor is one of the most popular and widely used micro servos for robotics, RC models, and DIY electronics projects. Known for its compact size, lightweight design, and ease of use, the SG90 is an excellent choice for applications where space and power consumption are limited.
With a weight of approximately 9 grams, the SG90 micro servo is ideal for small robotic mechanisms, educational projects, and battery-powered systems. It supports approximately 180-degree rotation and is controlled using standard PWM (Pulse Width Modulation) signals, allowing precise angular control using common microcontrollers.
The Tower Pro SG90 operates at 4.8V to 6V DC, making it compatible with popular development boards such as Arduino UNO, ESP32 development boards, ESP8266 NodeMCU, and Raspberry Pi. Due to its low current requirement, it is especially suitable for student projects, beginner robotics kits, and training programs.
This servo motor is commonly used in line-following robots, obstacle-avoiding robots, small robotic arms, pan-tilt camera mounts, and RC airplanes. For beginners building complete robotics systems, the SG90 pairs well with components such as robot chassis kits, servo testers, and external power modules.
On Vihaan IoT Gateway / DeviceBay, the Tower Pro SG90 micro servo motor complements popular products like Arduino boards, robotics sensors, and DIY electronics kits, allowing users to source all required components from a single platform. If you are working on projects that require higher torque, you can also explore our range of high torque servo motors and robotics motors.
⚠️ Note: The SG90 micro servo is recommended for light-load applications only. For heavier loads or continuous-duty applications, consider using a metal gear or high torque servo motor with appropriate power supply support.
