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

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

Good so far, all 5 work.

Item is of champion quality. Decorous packaging. Swift delivery. Solid seller. A+

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

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

Work well with small stepper.

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

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

worked right out of box. no bent pins

Four out the five worked fine. The fifth one was all over the place when adjusts were made. Fortunately I only needed the four.
