HiLetgo 4pcs L298N Motor Driver Controller Board Module Stepper Motor DC Dual H-Bridge for Arduino Smart Car Power UNO MEGA R3 Mega2560

So far I'm only using this to drive a small linear actuator with an Arduino and it does the job well. All of the heatsinks on my units are fully connected so no obvious issues with quality from my experience. Getting 4 for this price was just a bonus.

Arrived as described, fast delivery, quality component. Used to control motors on a hobby model car. Satisfied with performance. Would buy again.

Worked great for low power linear actuator. Not so great on bigger stepper motor, but thats my fault for not reading specs

These are great little modules for the price. Easily control speed and direction of two DC motors or parallel the outputs for more current. The only problem I had was with the poor quality control of the heatsink attach. There was a significant gap between the heatsink and the thermal tab. There is also no thermal grease or thermal pad between the heatsink and the tab. This caused the part to overheat with just 30% of specified loading. Fortunately, the solution was simply to torque down the screw until the tab was pulled tight against the heat sink. There was a smaller gap on all the modules I purchased, each slightly different which indicates poor process control. Also, I recommend injecting a small amount of thermal paste in the gap prior to tightening the screw. This will significantly improve thermal conductivity to the heatsink. If not for these issues I would have rated this a 5 star.

Great choice for a small (dual!) h-bridge board that will arrive quickly.This board brings out all of the pins for the L298 while adding the required passive components.If you read the L298 datasheet, you should be able to easily use this board.Also I am able to use 3.3V for logic.

Cheap, reliable, efficient. It made my motors work and was very easy to use. Couldn't ask for more.

If you need L298N's, these are fine. All four worked fine. There are newer alternatives available for the job (e.g., TB6612X's), but these seem to handle heat better.

I got these for a few bipolar stepper motors despite the negative comments about using them for stepper motors. The wiring is pretty simple, anything higher than 12V on the driver input, take the 5V enable jumper out or it will fry that regulator, run 5V power from the Arduino. My supply is 24V 2A max, had some issues with getting it to spin correctly and a lot of others are also reporting this problem, the issue with Bipolar stepper motors is, you have to shift the phase of the coils about 8 times in a particular order, having 2x2 high on some steps to make it work. Have to do the research on your motor and how it is wired and what its RAW logic input looks like. Mine ended up being a super weird combo but after drawing it on a piece of paper to see how the coils would produce polarity and how it would make the steps or even the errors, made perfect sense. The built in Arduio <stepper.h> library will not work with Bipolar stepper motors, the Unipolar stepper motors with the 5 wires does work, but that is because it is just P1, P2, P3, P4 right down the line for one direction and 4, 3, 2, 1 for the opposite direction. This is NOT the case with Bipolar steppers. The only thing I actually changed was I put a 24V drop down converter and have it set to 6.0V and going to the VIN pin of my arduino. Other than that, I am running a full 24V into the controller and out to the motors. I did notice running it at 24V does make it heat up A LOT, but adding a small fan to mine solved that pretty well. I am currently doing a work load test by just running an old motor in one direction for 2 seconds, then back the other, and repeat. I want to see if these chips can handle a long work time.Update 4-7-22: they work fairly well with super low average motors but nothing more than about 4A I have found. Fried 3 of them in the same spot on the bottom.
