L298N Motor Drive Controller Board Module Dual H Bridge DC Stepper For Arduino

I needed it to control a motor through a computer control board and it worked nicely.

This driver component is great. And it's super easy to use. Its designed to power two small electric engines (like ones you might use to turn wheels), but I use it to power four and it works great. I've had absolutely no problems using it AND the fact that you don't need to program it at all is a huge plus.

Needed to use it to drive a stepper motor in both single steps and "continuously." It won't do microsteping (which I don't need) but its enable inputs allow it to be PWM's to reduce the magnetic field's duty cycle, greatly limiting heating and noise from the stepper. It won't automatically shut off current to the motor when you aren't running it but you can do that via software (which is what I do), the heatsink barely gets warm using a NEMA 23 stepper.Anyway, this is embedded in a water treatment system to microdose my outside water connections (hoses and sprinklers) with polyphosphate to sequester iron. It runs whenever we use outside water and has been a reliable core part of the system for more than nine months now. Would buy it again, it's a great value and its limitations can easily be handled with a little software.

I almost gave this 3 stars, but because of its reliability, I decided on 4. The thing works great with raspberry pis. I've used these to control motors and LEDs (they output PWM afterall) and they work great. The build quality is questionable on some of them, so I think QC is a bit lacking, but they all seem to work. The only real complaint I have is with the 5v DC regulator. A common use case for these is to drive motors using micro-controllers (or raspis) and use the 5v output on these to power the micro-controller. That works fine, but the regulator gets very hot when doing that regardless of the current draw. I haven't confirmed this, but my suspicion is that the 5V regulator isn't a switching regulator, and is just burning off the voltage difference between your supply and 5v. This is an odd design choice considering that the whole board itself is a form of switching regulator (PWM). But, as I said, the reliability of these helped me overlook that. I've put these in unconditioned spaces without any overheating issues (they get scorching hot, but keep on ticking). Would recommend for any hobby or small electronic projects (just don't burn yourself if you use the 5v output).

I used this product for my raspberry pi so much that it became easy to remember the name "l298N Dual-H Bridge". This works for all sorts of motors, and the step-down voltage makes it convenient to power the raspberry pi with too; by plugging the 5V GPIO pin of the pi with this motor driver, I could power the pi with the same source as the motors! These worked great for my applications, and I continue to use them years after I first bought them. Because of their consistently good performance, I leave this review.

Very useful when working on a reverse wheel system (i.e. reversing the wheel of an rc car), and comes with not one, but TWO reversing motors. Simple system, and very cheap and efficient.

it gets the job done, but the screw terminal blocks could be much better.

Very easy to use
