SG90 360° Rotation Servo Motor for Arduino

SG90 360° Rotation Servo Motor for Arduino – a compact, high‑precision hobby servo that’s been upgraded with a continuous‑rotation gearbox, allowing full 360° (and beyond) motion control via simple PWM signals. Designed to plug straight into any Arduino‑compatible board, the SG90 delivers smooth, reliable torque in a lightweight 9 g package, making it the perfect bridge between classic servo teaching and the world of stepper‑style motion.

With this motor, students dive into core STEAM concepts: they’ll program pulse‑width modulation, explore gear ratios and torque calculations, and experiment with feedback loops to achieve precise positioning or speed control. The hands‑on experience reinforces physics (rotational dynamics), engineering (mechanical design and CAD), coding (C/C++/Python libraries), and mathematics (angle‑to‑pulse conversion).

Key Features

• Continuous‑rotation 360° capability with adjustable speed and direction
• 1.8 kg·cm stall torque at 4.8 V, ideal for lightweight robotics and animatronics
• Metal‑gear reinforcement for durability under repeated cycles
• Built‑in three‑wire connector (signal, VCC, GND) for plug‑and‑play with Arduino, Raspberry Pi, or ESP boards
• Compact 22 mm × 12 mm form factor, easy to mount on 3‑D‑printed frames or breadboard prototypes

Why It’s Great for STEAM Education
The SG90 360° servo turns abstract concepts into tangible results, letting learners see immediate cause‑and‑effect as they tweak code and watch a wheel spin or a robotic arm swivel. Its low cost and compatibility with widely used Arduino ecosystems lower the barrier to entry, encouraging interdisciplinary projects from kinetic art installations to autonomous vehicles, while fostering problem‑solving, iterative design, and collaborative teamwork. By integrating electronics, programming, and mechanical engineering in a single, versatile component, the SG90 accelerates the STEAM learning journey from theory to real‑world invention.
