Precision Motion for Your DIY Robotics
Whether you are building a custom robotic arm, a pan-tilt camera mount, or steering systems for RC models, precise motor control is essential. The SG90 Micro Servo provides accurate 180-degree positional rotation, allowing you to program exact angles using standard PWM signals. With a rapid response speed of 0.12 - 0.13 seconds per 60 degrees, your mechanisms will react instantly to your code, ensuring smooth and lifelike movements.
Lightweight Design, Heavyweight Torque
Don't let its tiny 9-gram footprint fool you. Encased in a durable plastic housing with high-quality plastic gears, this micro servo packs a punch. It operates efficiently on a standard 3.5V to 6V power supply and generates a reliable working torque of 1.6 kg/cm . This makes it strong enough to actuate flaps on fixed-wing RC aircraft, control small robotic joints, or trigger smart home locking mechanisms without adding unnecessary weight to your build.
Seamless Microcontroller Integration
Getting started with the SG90 is incredibly straightforward. It features a universally accepted JR/FUTABA style 3-pin connector, making wiring a breeze. Simply connect the Brown wire to Ground (GND), the Red wire to Power (VCC), and the Orange wire to your microcontroller's PWM signal pin. It is natively supported by popular libraries in Arduino IDE, MicroPython, and MakeCode for Micro:bit, allowing beginners and experts alike to get their motors spinning in minutes.

FAQ Section
FAQ Section
- Is this a continuous rotation (360°) servo?No, this specific SG90 model is a positional 180-degree servo. It is designed to move to specific angles between -90° and +90° based on the PWM signal you send it. It cannot spin continuously in one direction.
- How do I program the angles using PWM?The servo requires a 20ms (50Hz) PWM signal. A pulse width of 0.5ms moves it to -90°, 1.5ms centers it at 0°, and 2.5ms moves it to +90°. Most Arduino and MicroPython servo libraries handle this math for you automatically!
- Can I power this directly from my Micro:bit or Arduino?While a single SG90 can usually be powered directly from the 3.3V or 5V pin of a microcontroller during light testing, motors draw significant current under load. If you are using multiple servos or putting them under heavy strain, we highly recommend using an external 5V power supply to prevent your board from resetting.
