HiLetgo 5pcs DRV8825 Stepper Motor Driver Module for 3D Printer RepRap 4 RAMPS1.4 StepStick

I bought 5 of these "DRV8825" step motor driver breakout boards. They all worked fine for me on 12V power, 16 micro-steps, and current limit set to 1 amp. However... you do need to set the current limit first thing, before trying to run the motor in your application. It appears that, as delivered, the current-setting potentiometer may be at some random position, which could easily be well above the max continuous amps/phase current specified for the motor or the DRV8825. If you just apply power without setting the current limit there's a good chance the current is set too high which will probably overheat the DRV8825 and fry it. I suspect this may be what's happening for some of the reviews where they report "the chip got hot after a few seconds and stopped working". Also, keep in mind the "DRV8825" chip supplied on these boards is a counterfit ''knockoff' of the actual TI part. It does appear to generally work OK for non-critical hobby use, but as reported in a couple of other reviews this knockoff chip does not meet many or all of the specifications of the TI part. Quick current set: Put the driver in your circuit, connected to the motor you are using. Apply power but don't try and make the motor move. Just measure the voltage on the metallic screw-top of the potentiometer. Current limit in amps = 2X the measured voltage. Example, if you measure 0.5 volts at the potentiometer the current limit will be set to 1.0 amps.

I'm using these in my projects now instead of the 4988 chips because you can get 1/32 stepping with these and it works. Do put the heatsink on because these do get hot. The labeling is a bit harder to read than the 4988 boards.

I’ve gone through all 5 and ordered more. I use them in Arduino projects. Makes stepper motor control SO easy.

Awful quality! Only 1 out of 5 came in sealed packaging — the rest were just thrown into a plastic bag. 3 out of 5 were non-functional, with the current limiter screw either jammed or stripped beyond use. On top of that, 3 out of 5 had bent legs, looking like they had already been used and ripped straight off a breadboard.

A great upgrade from the a4988 and much more power with smoother operation. These have performed flawlessly for me.

I use these with a CNC shield v3. They are very easy to set the current to your desired value and are perfect for a small CNC. I have mine set at 1.2 amps. I give this a 4star because one of the DRV8825 I recieved only goes in one direction. I only needed 4 for my project and the price is very good.

Very happy with this.

These drivers are working well. Packaged well and arrived quickly. I would buy again if needed.

Tout probablement correct pour un remplacement d’imprimante. Les driver ne sont pas des versions originales de Texas Instruments. Il ny a aucune écriture sur le dessus et sont tout probablement des répliques. J’ai testé a 24V pour 1A de sortie a un Nema 17 et la chip devient extrêmement brûlante même avec un système de refroidissement. Vraiment déçu que se problème persiste, sinon tout fonctionne correctement.

My stepper motors are rated for 1.8A, so I calibrated one of the DRV8825 to 90% of that for safety: 1.8 x 5 x 0.1 x 90% = 0.81V However, it was heating up and died with a bright flash in under half hour in a hold mode. I also found it very noisy at 1/8 step, while the other DRV8825 I have are much quieter at this setting. Radiators have a different (thin and white, not black and goopy) adhesive and separate from the chips without any effort at all, so I am not sure if they are any good. Though I can be wrong Disappointed. 1 star and consider returning. Will test another one and decide UPDATE: Second DRV8825's connectors are soldered at an angle to such a degree that one side misses the headers on the PCB completely. Poor quality control
