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

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.

It works well, but way too expensive for a single unit. I hadn't realised until it was too late to cancel how much more these are than the multi packa elsewhere.

Non offrirà grandi prestazioni, ma mi ha permesso di creare un mezzo robottino tramite arduino di tutto rispetto. Il modello che mi aveva procurato il mio negoziante era saldato malissimo e non funzionava.

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.
