Waveshare Micro Servo MG90S with Metal Gear

The small MG90S micro servo from Waveshare (WS-MG90S) has robust metal gears and runs without problems with the Arduino Servo library. For several servos, there is the motor shield or the servo driver with 16 channels.

Recommended alternative with plastic gears: Waveshare Micro Servo 9G / SG90

Recommended Accessories:

• 16-Channel PWM / Servo Driver I2C (PCA9685)
• Motor Control Shield for Arduino V1.0 with L293D
• Servo Cable Servo Extension Cable AWG26 300mm
• Dupont Cable M-M 20cm 20 Pieces

Features:

• Controlled via PWM
• Rotation angle 180°
• Metal gears
• 3-pin socket on the cable
• For several servos, use a separate 5 V supply and connect GND to the Arduino

Application Examples:

• Small robots and robot arms
• Moving flaps and pointers
• Model making
