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

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.

Couldn’t get a full set that worked!

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.

Just as loud as big brand a4988s (loud) and have okay heat dissipation but are very reliable, and will get you out of a pinch if any of your quieter steppers decide to die.

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

If its a low grade hobby project, sure they work but theyre janky. Glitchy and prone to popping. I prefer using real drivers. This was just a waste of money and time for me as my project called for more precision and better control.

3 out 5 burned right out of electrostatic bag, all of them came out of the factory with corrosion.

Still in use today

Work well with small stepper.
