SG90 9g Micro Servo Motor 180°

⚙️ SG90 9g Micro Servo — 180°

The SG90 is the classic 9-gram micro servo for hobby robotics. It gives you about 180° of positional rotation controlled by a standard PWM signal, and it fits into tight builds where a full-size servo would not.

✨ Key Features

• Lightweight 9 g micro servo with plastic gears
• 180° rotation range, controlled by a standard 50 Hz PWM signal
• Runs directly from 4.8–6V — works well with a 5V supply
• Universal 3-wire connector (brown = GND, red = VCC, orange = signal)
• Includes three servo horns and mounting screws
• Transparent blue case with a white output shaft

🔬 Specifications

• Weight: approx. 9 g
• Dimensions: approx. 23 × 12.2 × 29 mm
• Operating voltage: 4.8–6V DC
• Stall torque: approx. 1.8 kg·cm at 4.8V, 2.2 kg·cm at 6V
• Speed: approx. 0.1 s per 60° at 4.8V
• Rotation: 180° positional
• Cable: 3-wire JR-style connector

🧰 Perfect for

• Robot arms, grippers and walking robots

• Pan/tilt camera mounts and sensor brackets

• RC models, planes and cars
• Arduino, ESP32 and Raspberry Pi projects
• Automated blinds, valves and small mechanisms

Tip: power servos from a separate 5V supply when using several at once, and share ground with the controller.
