Description: 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.

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.
