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.

worked right out of box. no bent pins

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

I worked but I don’t like the heat sink they use the 3M double side tape to stick on the chips

At least one of the five didnt work...Im only using two so I am unsure of the last twos functionality.

Tried two. Both work with NEMA 17.

Really wish these product listings came with a technical data sheet or instructions - I killed two of these drivers before figuring out that you CANNOT disconnect ANY motor pins while the driver is under power, otherwise you are likely to fry the circuit. Otherwise they work well, are very small, and are great for reducing motor control to only two pins.

Still in use today

Don’t buy, half didn’t work and one managed to burn up my main board, just go with tmc drivers you will save money in the long run

Works great with stepper motors
