Review on 🔌 HiLetgo 5pcs ULN2003 28BYJ-48 4-Phase Stepper Motor Bundle with 5V Drive Board for Arduino, PI, PIC & Raspberry Pi by Amber Loridon

When you think of a stepper motor, you think of precision. What I mean is that you usually want a stepper motor instead of a standard DC motor. I bought them to create an EggBot clone that I saw on Thingiverse. I will up front say that the motors and circuit boards work well in terms of connection and movement. At least for accuracy. These engines leave a lot to be desired. There is too much play in the shaft for accurate positioning, especially for the accuracy required of a plotter. If your project doesn't require precision, they will likely suit you. However, if you are trying to build any type of CNC machine - CNC; 3D printer; EggBot; laser engraver; etc - you are better off spending the extra money and using NEMA steppers. However, it was a cheap way to catch EggBot fever. I will use what I learned to rebuild my own NEMA based plotter so it wasn't a waste of money. As always, your result may vary.
