They all worked OK. Typical quality for this category of item.
5 out of 5 were usable. I use a lot of these, so I know that's well above average in the DOA department. Packing is typical with several layers of bubble wrap and a soft envelope, got no bent pins this time. Each driver had its own anti-static bag, that's a plus. if you're new to these, be sure to turn the current-set pot all the way clockwise. Typically these come set to mid range, which is equivalent to about 2 or more amp which will lead to a thermal shut down in a few seconds. You can consult the 'tube to find out how to set power levels the tech way. Or if you are without a meter or just pragmatic, you can power up with a motor attached and some simple Arduino program delivering pulses. At first the motor won't move because you've set the current to 0 amps. Turn the pot counter clockwise SLOWLY. At some point (and it won't take much turning!) the motor will start to run. Pinch the shaft hard with your fingers and continue increasing the current until you just barely can't stall the motor. At that point you are likely to be at, or slightly below, the proper current rating for a middle sized NEMA 17 motor. Touch your fingertip to the NEG power connector to discharge any static. Gently touch your finger to the top of the chip...it should feel a little warm, but not hot! If it's hot, reduce the current until you find some sweet spot balancing heat and motor performance. Best practice calls for using a heat sink, the ones that come with this kit are (typical of all kits on Amazon) kinda small, but better than nothing. The kit ones will let you set current about 0.1 amp higher than without. If you're really ambitious, but some tall heatsinks, sand of the anodize off the contact surface of the sinks to expose bare aluminum, and glue the sink to the chip with Arctic Alumina Thermal Adhesive, which is actually a two-part epoxy. It sets fully in about 15 minutes. That will let these drivers max out close to 1.9 or 2.0 amps without thermal shutdown, which is very impressive. And it will prevent the heatsink from shifting position which can happen with the spongy, peel off adhesive pads that come with the sinks. It just takes a tiny dab, grain of rice size or even smaller. A tiny dab will do ya, gramps. That stuff works really good, and although expensive one kit will do a LOT of heatsinks, so call all your friends for an upgrade party... wear masks please. PS, sometimes when adjusting current the driver will do a thermal shutdown. Don't despair, and don't toss it. Turn everything off, give it a 5 minute rest, and it's good as new. PS, it is not entirely an old-wives tail that powering up these drivers without a motor attached will kill them. Be safe and don't tempt fate. And be darned sure you've got these things plugged in with the right orientation, the old 180 degree error is all too easy.

Functional and good price
I bought these for my custom Eggbot controller board as an upgrade from the A4988 stepper drivers. They worked quite well driving some NEMA 17 stepper motors. Setting VREF was as easy as the A4988 cousins, as long as you remember that the potentiometer is in the opposite corner. I recommend putting the heat sinks on before using though. They can get quite warm with prolonged usage.

Works great, bit hard to calibrate
Those are the real deal and work well. Packaging is a bit confusing since mine said A4988 on the bag, but the components were DRV8825s. The calibration screw is pretty sensitive and it can be hard to hit the current limit for 0.4A motors

Work great. Right price.
These stepper motors worked perfect in my SKR 1.3 for my CNC machine. One was bad in the first order, but a replacement was quickly sent and everything is working as expected.

Nice stepper motor driver.
They drive by stepper Motors. They do it very well.

Burn out very quickly.
I've tried all 5 drivers in the pack I got, 4 burned out very quickly, at any current setting, the 5th never worked at all. The heatsink gets hot almost as soon as you connect the power supply. One out of 5 has a defective potentiometer. Another, out of the box, has only 2 Ohms resistance between positive and negative voltage input. You can still adjust the current, but the end points have broken, so you never really know where you are. I've checked with an expert in how to wire these, we set the current super low, hardly any holding torque on the motor at all as a result. Yet, best we got was a few minutes of action before the thing was burned out. At least for me, they don't work.

They work well enough.
They work well enough. Just be aware that every DRV8825 ever made has a slight "hiccup." It is not noticeable in most cases. If used in a 3D printer's extruder, however, they will create "zebra stripes" in the walls of your prints. As long as your application does not require extremely smooth movement, they will work fine.

It's functional but needs improvement
It works but it gets heated a lot. We have to adjust the variable rheostat properly otherwise the chip will burn which happened to me. It gets hot a lot so beware

Es erroneo el anuncio solo son 5
Es es driver correcto sin embargo son solo 5 no llegan 50
