SG90 Micro Servo Motor (9g)

Description

Compact Power & Accuracy

Despite its miniature size, the SG90 packs a punch with a stall torque of 1.8 kg/cm at 4.8V. This makes it strong enough to move small mechanical linkages, grippers, and steering systems. At RoboShop BD, we ensure these servos come with the complete accessory kit, including three different “horns” (arms) and mounting screws, so you can adapt the motor to your specific mechanical needs immediately.

Easy 3-Pin Interface

The SG90 features a standard 3-pin “S-type” connector that is compatible with almost all RC receivers and microcontroller headers. The wiring is color-coded for simplicity: Brown (Ground), Red (VCC), and Orange (PWM Signal). By sending a pulse-width modulated (PWM) signal with a 20ms period, you can command the motor to hold any position within its 180-degree range with high repeatable accuracy.

Key Features

• Ultra-Lightweight: Only 9g, making it ideal for drones and weight-sensitive RC models.

• 180° Rotational Range: Full half-circle movement for versatile mechanical applications.

• Plug-and-Play: Works seamlessly with the standard Servo.h Arduino library.

• Durable POM Gears: High-quality plastic gears provide a balance of smoothness and strength.

• Low Current Draw: Can often be powered directly from a microcontroller’s 5V pin (for single servo use).

• Wide Compatibility: Fits standard 0.1″ (2.54mm) male headers.
