HiLetgo 5pcs A4988 Stepstick Stepper Motor Driver Module with Heat Sink for 3D Printer Reprap Suitable for Mendel Huxley Arduino

I used these for driving my stepper motor and found it very useful instead of driving the H bridge directly this gives you direction and step control signals. It has an adjustable current limit which my former H bridge controllers didnt. It worked well with the AccelStepper Arduino library. The only negative is that they are very easy to burn out. I was driving the motor with 24V and any loose connection to the motor would burn out the controller. When it went it would, somehow, take my Arduino out as well. I went through a few sets of Arduino and controller before I figured it out. Dont forget to put a capacitor on the VMOT as well. When it is working it works great though.

Couldn’t get a full set that worked!

first shipment didnt work, sending back, replacement on its way.

Good so far, all 5 work.

Still in use today

These work well. I used them as replacements for my 3d printer
