This is a great first stepper motor, good for small projects and experimenting with steppers.  This uni-polar motor has a built in mounting plate with two mounting holes. There are only 8 steps per revolution, but inside is a 1/64 reduction gear set. What this means is that there are really 8*64 steps per revolution = 512 steps! The shaft is flattened so its easy to attach stuff to it with a set-screw.  A perfect first stepper motor and works well with the Motor Shield for Arduino.

The gearing has a few side effects which are important to note.  First, you can turn the stepper by hand but not as smoothly as an un-geared stepper.  It also means you shouldn't use interleaved or micro-stepping to control or it will take forever to turn.  Instead use single or double stepping.  The torque is fairly high but its slower than un-geared steppers - we maxed out at about 80 RPM by over-driving it a bit with 9VDC.
