There is no doubt the stepper motors are one of the most used parts in robotics by creators and hobbyists. Sure, countless of them are available and compatible with prototyping boards such as Arduino or Raspberry Pi, ranging from several dollars and up to tens of dollars. It’s no wonder that the creators and hobbyists used stepper motors and had built thousands of projects on its sturdy back.

Three weeks ago we had presented a hand-picked collection of Arduino motor shields for every budget that also includes a bunch of stepper motor shields. Now it’s time for a new collection of stepper motors in robotics. For the sake of this article, let’s lay out a guide of the best stepper motors in a range of prices to suit pretty much any budget.
