Our Review
For $81.94 CAD, the FEETECH FS90MR 360 Degree Micro Servo 9g, Small Metal Gear Continuous Rotation Servo Motor MG90 Mini Servos for Arduino RC Helicopter Airplane Car Robot Controls packs respectable specs: Torque: 15 kg-cm, Operating Voltage: 6V - 7.4V, Speed: 0.14 sec/60°. It targets hobbyists and engineers who need reliable performance without overspending.
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 FEETECH FS90MR 360 Degree Micro Servo 9g, Small Metal Gear Continuous Rotation Servo Motor MG90 Mini Servos for Arduino RC Helicopter Airplane Car Robot Controls 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
- Standard PWM control works with any Arduino/ESP32 board
- Wide operating voltage range supports various power sources
- Metal gear train handles high-torque loads without stripping
- Quick response time for real-time control applications
Watch Out For
- Plastic spline wears faster than metal alternatives
- Jitter at rest if PWM signal has noise
- Internal potentiometer wears over thousands of cycles
