KINGPRINT DRV8825 Stepper Motor Driver Module with Heat Sink for 3D Printer Rrerap Ramps 1.4 A4988 (Pack of 5pcs)

1 dead on arrival Also missing one heatsink The other four are working seem to be no more noisy than other steppers I have heard

They work very well. Only issue is the adjustment screw on 2 of them does not turn any more.

works as advertised. no issues so far!

Great DVR8825 drivers. Noticable difference in print quality on my 3D printer.

These work just fine. Remember to adjust the screw for what you need. If running for a long time keep a fan blowing on them or keep a few spares on hand.

Excellent product. Was shocked to find out it supports 1/32 stepping. As always, very your voltage before attaching your steppers. Mine were all around 0.6V except one that was at 2+V which could have fried my motor.

No documentation make sure whatever you are replacing they are going in the correct direction as these are opposite of the ones you might be upgrading.

Got 5 for 15 bucks or so Work like a charm will be ordering more...

Cannot beat the price but it does not do much good when 1 was no good from the begin another failed in 30 minutes and so far the other 3 seem ok at this point. I have had better luck with the A4988’s

These little boards are a great replacement for the standard 16 microstep driver and provide a 32 step option. If used to increase microsteps and quiet the stepper motors, Marlin software or printer settings must be changed for double the step rate or measurements will be off by 2X.
