A3967 Stepper Motor driver Module

Wired up a small bipolar motor for a CNC project and the microstepping feature made it run noticeably smoother than my old driver. The compact size is perfect for tight spaces on my breadboard.

Running two NEMA 17 motors on these with the microstep settings was surprisingly smooth, and the compact board size made it easy to fit into my 3D printer enclosure. The driver handled the current without overheating during a 45-minute test run, which is exactly what I needed for a reliable CNC upgr

The onboard potentiometer made adjusting current limits a breeze, and it drove my NEMA17 smoothly through several microstepping modes without any skipped steps. I've paired it with an Arduino and a simple power supply, and for under ten bucks, this driver handles all my small 3D printer and CNC expe
