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

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

3 of the h5 packages were already open. I have not tested but I am worried they are blown. :(

Works good made printer run again just didnt look if they were silent

The heat sinks are too big to install without worrying about causing a short by touching pins. Though, all chips like this have the same issue.

Heres what starred items Amazon wanted me to rate for these stepper drivers. Noise level? Adhesion? Warmth? The vendor should get on them for this nonsense and the poor ratings it might bring. I guess they know not what they sell! But Ill say in defense of the seller and the product that ... Thes are pretty generic, and these work as expected and the delivery was fast.

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

They sent me 5, but 3 where in the same pcb and the other 2 in another pcb. Impossible to break without ruining the component. Impossible to put it on a driver of 4. Impossible to setup if your project has motor in different places separated by even small distances. to much wiring. Frustrating.

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

Ive used these in two of my printers and they work great. They obviously arent the quietest, fastest, or best option for everyone, but they are a fantastic choice for the price.

Great price, drive NEMA 17 in an Arduino CNC shield perfectly. I use the CNC shield, but not for a CNC machine, just for the mounting and pin connections. Highly recommend both.
