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

I bought these to replace some other DRV8825s I purchased off of eBay that would miss steps. These work great and are relatively quiet. Im using these on a RAMPS 1.4 board with an Arduino MEGA 2560.

Ive used 1 out of the 5 drivers so far without any issues. Initially my order was shorted 1 item out of the 5. I contacted the seller and they sent out the missing piece. Overall I would buy from the seller again.

Works fine on my genmitsu pro.

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.

Worked great. No problems

They worked OK but not an improvement over stock A4988s

Defected on first installation. VREF is not adjustable.

works as advertised. no issues so far!

Prompt delivery, stepper drivers worked as replacements for A4988 drivers with minor software change to accomodate 1/32 stepping.
