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

    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

    I bought these for lab use to test/analyze motion controller behaviors only to discover that these little drivers need much support circuitry before theyll function. These drivers will also drive from their own noise, meaning once stepping has started it might never stop! These might be okay drivers for those who know them well, but if youre a first time user of these like me I say AVOID!

    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.

    Dont know if I got unlucky or what, but one of them literally exploded on me and blew a chunk of the chip out

    Pretty solid. Its a straight pololu rip-off, so I kind of feel bad cheaping out on it, but the budget was tight for a school project. I killed a couple (as well as an arduino) trying to drive a stepper over 24 volts, so be careful, and keep it several inches from the microcontroller on your board. If theyre packed together, the pins can arc to the arduino and fry both.

    I installed these in an Anycubic Kossel liner plus delta printer and it has made a big difference in the amount of heat that is generated. I have theses set for about .7 amps and they runs silent and cool, the steppers no longer make the whine and are cool to the touch after a 2 hour print. I replaced the heatsinks with something that was a bit larger and added a fan to the enclosure. No problems with any of them so far.

    Defected on first installation. VREF is not adjustable.

    UPDATE 03/21/2019 New Title says it all. Arrived early February and installed in a RAMPS board, set to 0.82MV and all good. Well, all good for about 16 hours of printing anyway. Just pulled them all out and have gone back to the A4988 after the second one failed. It is a pity as they quietened the printing down a lot with the 1/32 Micro-stepping. I am a bit surprised as I am a fan of Kingprint with with several main boards that have proven to be exceptionally reliable, but this latest batch of drivers -- not so much it seems. This is the second batch of DRV8825 I have had from them. The first lot bought in mid 2018 have been excellent and still running reliably. Will order from a different supplier and try again.

1.A simple steps and direction control interface
2.Six different steps resolutions: full step, half step, 1/4-step1/8-step1/16-step, 1/32-step
3.CAN interface directly with 3.3 V and 5 V systems
4.Over-temperature thermal shutdown, overcurrent shutdown, undervoltage lockout
5.Short to ground short circuit load protection
6.4 Layer 2 oz copper PCB, in order to improve heat dissipation
7.Exposed solder ground below the bottom of the driver IC on the printed circuit board pad
8.Module size, pin and interface matching A4988 stepper motor driver operators in many ways
9.Adjustable current control lets you set a potentiometer, which lets you use the stepper motor"s rated voltage or more, in order to achieve a higher rate of maximum output current step
10.Maximum 45 V supply voltage

Package Included:

5* DRV8825 Stepper Motor Driver Module
5*Heat Sink
