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

Just what I needed for my laser engraver

good item

works but noisy

These were great and did work very well. I did howeer, have an issue where one of these did not work at all. Considering they were brand new, I thought they would be fine so spend a long time replacing my stepper, controller and wires before I figured out the source of the problem. I didn't need all 5 so it worked out okay however, It would have been nice if all of the products I purchased did function out of the box

Must have had a bad batch. Returned

Seem ok but not sure the heatsink will fit without modification to avoid shorting component.

Goed product

Der Artikel ist wie beschrieben und wurde pünktlich geliefert. Mit diesem Händler immer wieder gerne.

Gud

Take care when fitting the heatsink not to let it touch other components! I'm testing my pan/tilt project *without* these heatsinks. No sign so far of the chip getting warm.

Für Experimente sehr gut geeignete Treiber. Sind zwar nicht die leisesten aber für manche Aufbauten spielt ja der Lärm der Motoren weniger eine Rolle als der Rest der Mechanik. Sind auch um einiges einfacher anzusteuern als die neueren Trinamic-Chips.
