The SG90 Mini Servo Motor (180 Degree) is the most popular choice for beginners and hobbyists worldwide. At Electrapac, we recommend this lightweight, reliable motor for small-scale robotics, RC planes, and Arduino projects where space is limited but precision is essential.
The SG90 is a tiny, high-quality actuator that can rotate approximately 180 degrees (90 in each direction). Unlike standard DC motors that spin continuously, a servo allows you to tell the motor exactly what angle to move to, making it the "go-to" component for steering and mechanical arms.
Featherweight Design: Weighing only 9 grams, it is perfect for aircraft and drones where every milligram matters.
Easy Arduino Integration: Compatible with the standard Servo.h library. You can control it using just one PWM pin.
Complete Accessory Kit: Every SG90 from
Low Power Consumption: It can typically be powered directly from an Arduino's 5V pin for simple tests (though an external 5V source is recommended for multiple servos).
High Versatility: Strong enough to move small linkages, open latches, or tilt cameras.
The SG90 uses a universal 3-pin connector with the following color codes:
Brown (GND): Connect to the Ground terminal.
Red (VCC): Connect to 4.8V - 6V Power.
Orange (Signal): Connect to a PWM-capable digital pin (e.g., Pin 9 on Arduino).
Pro-Tip: If the motor "jitters" or resets your Arduino, it is likely drawing too much current. Use a dedicated 5V power supply and remember to connect the GND of the external power to the GND of the Arduino.
Robotics: Finger movement in robotic hands or neck joints for bipedal robots.
RC Models: Controlling ailerons, elevators, and rudders on park-flyer RC planes.
Security: Building automatic door latches or safe-locking mechanisms.
IoT Projects: Automated window blinds or pan-tilt brackets for security cameras.
We source SG90 servos with smooth internal gear movement to ensure you don't face "skipping" or stripped gears during your build. Find this motor, jumper wires, and Arduino kits at
