TowerPro SG90 180 Servo Motor Ideal for Arduino, Robots & DIY Projects

The TowerPro SG90 180 Servo Motor Ideal for Arduino, Robots & DIY Projects is a lightweight, affordable micro servo providing precise 180-degree angular control via standard PWM signals. It is the most popular servo for Arduino projects worldwide.

Key Features

• Ultra-lightweight at just 9 grams
• 180-degree rotation with precise angular control
• 1.8 kg·cm torque at 4.8V operating voltage
• Standard PWM control (50Hz, 0.5ms-2.5ms pulse)
• Nylon gears for quiet operation
• Quick response with 0.12s/60° speed
• Plug-and-play with Arduino Servo library

Technical Specifications

Applications

• Robot steering for cars and rovers
• Camera pan/tilt mechanisms
• Sensor positioning and scanning
• RC planes/cars control surfaces
• Animatronics and puppetry
• Gripper control and robotic arms

Pinout

• Brown wire: Ground (GND)
• Red wire: Power (+4.8V to +6V)
• Orange/Yellow wire: Signal (PWM input)

Important Notes

• Do not stall the servo for long periods – overheating will damage motor
• Use external 5V supply for multiple servos – USB may not provide enough current
• Current draw spikes during movement – add capacitor near power pins
• Nylon gears can strip under excessive load – consider MG90S for metal gears
• Standard PWM: 50Hz frequency, 0.5ms=0°, 1.5ms=90°, 2.5ms=180°
