Qunqi L298N Motor Drive Controller Board Module Dual H Bridge DC Stepper For Arduino
- Dual-channel H-bridge driver working mode creates higher working efficiency,L298N as main chip.Can drive one 2-phase stepper motor, one 4-phase stepper motor or two DC motors.
- To avoid damage the voltage stabilizing chip, please use an external 5V logic supply when using more than 12V driving voltage
- Use large-capacity filter capacitors and diode with freewheeling protection function, increasing reliability
- High working power to 46v,large current can reach 3A MAX and continue current is 2A, power to 25w.
- Large capacity filter capacitance,afterflow protection diode, more stable and reliable.

Exactly what I needed
Using it for a project I'm working on. Works great so far. Does get pretty hot when pushing a stepper. I used fan for cooling. Plenty of online documentation for setup

Big, but easy to use!
There's alot of great documentation on these for use with Arduino, which made it extremely easy to drive my giant 12 volt DC gear motors. The left and right channels are also very consistent with eachother after calibrating your project with a little trial and error coding.

These drivers are excellent. I had a problem with some nema 17 stepper motors pulling a tad over 2 amps at times. These drivers are rated for 2 amps and i have over-loaded them briefly (I don;t recommend doing that) and they didn't fry. I had them in a place where the heat sinks were minimally air-cooled, and maybe that helped. The packaging was okay and the delivery was swift (the next day). I will buy these again, when needed. In fact, I may even buy these particular drivers when i only need one amp. Be advised, when loaded heavy, these heat sinks will get very hot.

Works nicely. Does have voltage drop is annoying
Works perfectly on my little robot I'm building. Took me some time to figure it out. But was able to find lots of good tutorials and documentation online for it. The only thing I dont like is the Voltage drop. At times it's gone to just over 2V. But I've worked out most of the kinks in my setup and now it runs like a top. I just need to find a use for the +5V output from logic chip. I'll use it to run something.

Works as described
I have this circuit hooked up to 2 60RPM motors and it works well. To power my motors, I have 8 AA batteries connected together to produce 12 V. It's hooked up to an Arduino. I bought all of this on Amazon.

Easy to wire
I purchased this Motor controller for my raspberry pi robot product. Easy to wire, small enough to mount anywhere. It's been almost a year now since my build and it is still working great.

Not the newest technology but works great for my application
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.

Great product, price, and delivery.
This is my first time using this board and it was very simple. It made it so easy to control a couple of DC motors with an Arduino that it was well worth the money (which was not a lot to begin with). Product arrived quickly also. Highly recommended.

Best for small motors that don't draw excessive
Driving 2A stepper motors with these, but I am regulating the current and voltage to make that happen. Best for small motors that don't draw excessive current

It works really well. I am using it with a NEMA 17 stepper motor. I had a software glitch in my code that left full current through both windings of the motor that made the heat sink get really hot, but there was no damage to the driver. I'd call that a very rugged device.
