STEPPER MOTOR 28BYJ-48

This small reduction 5-wire “28BYJ-48” stepper motor is a fantastic first stepper motor, great for experimenting with your raspberry pi and steppers. This uni-polar motor has a built in mounting plate with two mounting holes, and the motor shaft is flattened so it’s easy to attach stuff with a set screw! There are only 8 steps per revolution, but inside is a 1/64 reduction gear set which means that there are really 8*64 steps per revolution = 512 steps! A perfect first stepper motor.
