The MG90S Mini Servo Motor is a compact and powerful micro servo featuring durable metal gears, allowing it to handle higher loads and provide greater reliability compared to standard plastic gear servos like the SG90.
With a 180° rotation range and fast operating speed, this servo is ideal for robotics, RC models, automation projects, and STEM applications requiring precise motion control.

💡 MG90S vs SG90
Unlike the SG90 (plastic gears), the MG90S uses metal gears, making it more durable and capable of handling heavier loads without premature wear.
⚠️ Important Notes
-
Use a stable external power supply when driving multiple servos.
-
Do not power directly from a microcontroller 5V pin.
-
Avoid mechanical overloading to prevent motor damage.
