28BYJ-48 Stepper Motor

This is a common and cheap stepper motor that is commonly distributed with a ULN2003 driver. This configuration only requires 4 GPIO pins (+GND and Power).

The 28BYJ-48 Stepper Motor has multiple variations, but the 1/64 geared is the most common variety. If you have one where the gear ratio is not supported, please open an issue and we can add the version.
