MG90S metal-gear micro servo motor

MG90S micro servo motor

A micro servo motor lets you operate a robotic arm, open a window or build other creative mechanisms!

This micro servo motor has metal gears instead of plastic gears, making it stronger, more precise and more wear-resistant than its smaller sibling, the SG90.

Here is a video comparing these two micro servo motors:

Servo motors are useful for moving their shaft to a specific position and holding it there. This servo can turn from 0 to 180 degrees and cannot make continuous revolutions.

Our MG90S servo motor has just 3 wires to connect: power, ground and a PWM control signal. When using it with an Arduino microcontroller, you can use this open-source  library to drive the motor.

Warranty and shipping

We do our best to test all electronics before sending them to you.
This helps us deliver good work and saves you unnecessary trouble during development. Faults can occur, but we see them very rarely. If there is a problem with the equipment you ordered, you can always contact us, and we will be happy to help resolve it. 

We dispatch from Aarhus to Denmark and Sweden. Shipping options and prices are shown at checkout. Delivery time depends on availability, destination and shipping method; contact us before ordering if you need an item by a specific date.

Travel, weight and torque can vary between MG90S suppliers. The stated 0–180° and torque figures are not calibrated guarantees for every unit. Start with a limited pulse range, avoid mechanical stalls and use a separate servo supply sized for start/stall current with common ground.
