These steppers are a great way to get things moving, especially when positioning and repeatability is a concern.
Note: This is a Unipolar stepper, meaning that if you are going to drive it with a bipolar stepper driver, you can ignore the yellow and white leads and drive it using the remaining four.
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.

I bought this motor for a DIY CNC machine with no experience with stepper motors or big DC motors. Overall, this is a solid motor. It's well-made and perfect for DIY projects. It's also pretty straight-forward learning how to operate it, although might require a little research if you don't know anything about stepper motors.
By using a 3VDC supply, I could avoid a lot of energy waste if a (power) drop resistor is inserted to the higher voltage supply. A buck converter with proper current output is a must. Why did I use a 3V stepper motor like this one? It is just a change of taste. So far, as stepper drivers, there are Arduino Uno + L298; and 4017 counter + power transistors. No robots or CNC devs yet, but it's fun.
We used two of these in a project a couple years ago, and they were the best price we could find for this amount of torque. We used them in as bipolar motors (so we ignored two of the wires) and drove them with some A4988 stepper drivers from Pololu (same chip as Sparkfun's Big Easy Driver) with a 12V power supply to the driver. We were only able to reliably run them at about 1.4A per phase (because of the drivers) so we didn't get to push these motors all the way to the 2A that they're rated for. However, they worked just fine and had plenty of torque for our project.
Bough this along with the EasyDriver and it worked just like it is supposed to. Plenty of torque for what I was trying to turn!
Stepper motor works great if you understand the coding process. You will need loctite or some other industrial adhesive to attach it to most things. The cylindrical, smooth machined shaft is otherwise a challenge to work with.
