28BYJ-48 unipolar stepper motor and ULN2003 controller

28BYJ-48 stepper motor + driver module driver, has a structure with two holes for mounting, and the motor shaft is flattened making it easy to connect with a set screw. The 28BYJ-48 engine handles 512 steps per revolution.

The 28BYJ-48 motor driver allows you to control a unipolar stepper motor with a maximum output current of up to 500 mA per channel.

This "28BYJ-48" stepper motor is a fantastic engine to experiment with your projects. This unipolar motor features a two-hole structure for mounting, and the motor shaft is flattened making it easy to connect things with an adjustment screw. There are only 8 steps per revolution, but inside is a 1/64 reduction gear set which means there are actually 8*64 steps per revolution equal to 512 steps.
