Stepper motors are great motors for position control. They can be found in desktop printers, plotters, 3d printers, CNC milling machines, and anything else requiring precise position control. Steppers are a special segment of brushless motors. They are purposely built for high-holding torque. This high-holding torque gives the user the ability to incrementally “step” to the next position. This results in a simple positioning system that doesn’t require an encoder. This makes stepper motor controllers very simple to build and use.
These stepper motors, in particular, are used with the Shapoko CNC machine and offer 125 oz.in of torque and 200 steps per revolution. Additionally, each motor has been equipped with extra long 600mm AWG22 wires, making them ideal for CNC applications.
Note: This is a Bipolar stepper.
This skill concerns mechanical and robotics knowledge. You may need to know how mechanical parts interact, how motors work, or how to use motor drivers and controllers.
Skill Level: Experienced - Your experiences should include working with stepper motors and feedback system. You may need to understand how encoders and more complex control systems work.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

It's working perfectly
I am very happy to owned product like this motor
This stepper motor is a great buy. Very sturdy/solid build in a compact design. Works as described and I have no complaints about it.
Ran it on 5 volts with Arduino motor shield. Nice and quiet and lots of torque!
I picked this one out not really knowing much about stepper motors, but I went for it thinking that it had the highest torque of any of the motors carried by SparkFun. I was not let down! I can't even stop it from rotating when holding it with both hands; maybe that's normal of stepper motors, but I was surprised at how strong it is. The one tricky thing is that the shaft is totally smooth, so attaching something might be a little tricky (though again, maybe this is normal).
(Also, on another note, this thing is quite heavy — and I did get my bag double-checked by the TSA agents when I was flying with it in my carry-on; haha)
