Adafruit Micro Servo - MG90D High Torque Metal Gear

Add more power to your robot with this metal-geared MG90D servo. The compact servo can rotate approximately 90 degrees, making it versatile and capable of fitting into tight spaces.

This servo integrates seamlessly with any servo code, hardware, or library. Ideal for those looking to make things move effortlessly without constructing a motor controller, thanks to its built-in feedback and gearbox. Though not as strong as standard servos, it performs excellently with the Motor Shield for Arduino or through direct wiring with the Servo library.

Accompanied by several horns and hardware, it offers ease of use. Remarkably, the servo holds its position even without an active signal, providing stability for various projects. For Arduino control, connect the yellow wire to pin 9 or 10 and utilize the Servo library.

Understand position settings with precision: "0" rotation with a 1.5ms pulse is the center, "90" (~2ms pulse) fully rotates to the right, and "-90" (~1ms pulse) fully rotates to the left. The orange or red middle wire supplies +5V power, while the brown or black wire connects to the ground.

The default pulse widths typically range from 1ms to 2ms, which can limit motion. It's recommended to experiment with manual pulse lengths—aim for 0.75ms to 2.25ms for extended range while carefully adjusting to prevent damage.
