SG90 Servo Motor - 9 gms Mini/Micro Servo Motor

SG90 Servo Motor - 9 gms Mini/Micro Servo Motor (180° Positional Control)

The SG90 Servo Motor is the quintessential choice for small-scale robotics and RC projects due to its unmatched combination of size, low weight (9 grams), and reliable performance. As a Mini/Micro Servo, it uses a standard 50 Hz PWM (Pulse Width Modulation) signal to achieve precise angular positioning—typically offering a range of 180° of motion. The servo contains a brushed DC motor, a reduction gearbox (often nylon gears), an internal control circuit, and a potentiometer that provides position feedback.

Operating efficiently between 4.8V and 6V DC, the SG90 delivers sufficient torque (approximately 1.8 kg-cm) to move light loads, making it perfect for steering surfaces in small RC planes, actuating robotic grippers, or controlling small linkages. Its easy-to-use 3-wire interface (Power, Ground, and Signal) makes it compatible with virtually any microcontroller platform, including Arduino, Raspberry Pi, and ESP32, requiring only a simple digital output pin to send the required PWM signal.
