Miuzei SG90 9g Micro Servo Motors 5-Pack for RC Cars, Arduino, and Robotics Projects

This 5-pack of Miuzei SG90 9g micro servo motors is built for small-scale remote control and robotics applications. Each servo runs on 4.8‑6V, producing 1.4 kg/cm of stall torque, and rotates through 180° at 0.09 sec/60° under no load at 4.8V. The metal gears and generic JR/Futaba connector make them easy to integrate into custom builds.

What setups work with the Miuzei SG90 servo?

These servos are compatible with Arduino and Raspberry Pi boards, as well as standard RC receivers using the JR/Futaba interface. Common projects include RC cars, airplanes, helicopters, drones, small robot arms, and DIY robotic platforms. The compact 9g size fits tight spaces where larger servos won't go.

Tips for using analog servos

These are analog servos, meaning they require a continuous PWM signal to hold position. The starting current draw exceeds 1A, so use a capable power supply. For best results, provide 4.8–6V and a steady 50 Hz PWM signal from your controller or RC receiver.

What’s in the box

• 5 × Miuzei SG90 9g micro servo motors
• No additional mounting hardware or horns are included (reuse from existing kits or buy separately)

Common questions

Do these servos work with Arduino?

Yes, they connect directly to Arduino PWM pins using standard servo libraries. Power the servos separately if driving multiple units.

What voltage should I use?

4.8–6.0V DC is required. A 5V supply from a BEC or voltage regulator is a typical choice.

Are they analog or digital?

Analog. They need a continuous PWM signal; they will not hold position without it.

Can I use them in a drone or helicopter?

Yes, they are suitable for micro drones, fixed-wing foamies, and small helicopter swashplates where lightweight servos are needed.
