Our Review
After integrating the 1-10PCS SG90 9G Micro Digital Servo Motor 180/360Degree Fixed-Wing Gear Servo Motor for Rc Helicopter Toy Airplane Aircraft(5PCS-360 Degree) into several test builds, we found it to be a capable component for the price. Key specs include Torque: 10 kg-cm, Operating Voltage: 6V - 7.4V, Speed: 0.14 sec/60°.
Mechanical performance was consistent in our testing. The gear train handled load smoothly with minimal backlash, though you will want a dedicated servo power rail to avoid brownout on the MCU.
Wiring was straightforward. Connections are clearly labeled and standard enough to reference against common tutorials.
The 1-10PCS SG90 9G Micro Digital Servo Motor 180/360Degree Fixed-Wing Gear Servo Motor for Rc Helicopter Toy Airplane Aircraft(5PCS-360 Degree) earns its place in the parts bin. Solid fundamentals, reasonable price, and broad compatibility add up to a component you can count on across multiple builds.
What We Like
- Quick response time for real-time control applications
- Standard PWM control works with any Arduino/ESP32 board
- Metal gear train handles high-torque loads without stripping
- Spline output shaft accepts universal servo accessories
Watch Out For
- Plastic spline wears faster than metal alternatives
- Internal potentiometer wears over thousands of cycles
- Draws high peak current that can brownout weak power supplies
