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

It works well but does not come with any directions if you look to the internet for help when it does not work at first.

If you want to power this from your Arduino, you must remove the single jumper above the other pins on the breakout board. On either side, you will also need to keep your jumpers Final phase Be sure that you are sending VCC via the left side. I felt like I was deciphering a combination lock when I discovered these requirements. I like the heat sink, but it is quite large and bulky so that it makes it difficult to seat the module in tight spaces. There are a few loose or loose screw terminals on the board, meaning that they shift when you screw them in. Hardware for attaching the board to the board must be M2. Otherwise, it does exactly what I wanted and I am happy.

PWM motors use a lot of pins and if you are using two, it will take up 6 of your Arduino's pins. Some Arduino pins do not To save code sharing time, to implement a common interface, as well as the methods for each controller, on your other projects with different controllers would be a good idea. It is simply a case of ensuring that the correct motor library is included It looks like this is my implementation for the Here is a link to the L298N motor controller. In some controllers, direction is determined by only a single pin. There are 2 pins on this one. The following code is for ]

I'm going to tell you what digitalWrite (dirpin+1, LOW) does.

It is easy to wire and compact enough for almost anywhere mounting. Over a year has now passed since I built the system, and it continues to work smoothly.

It was very close to getting 3 stars, but I decided to give it a 4 because of its reliability. I used it with a raspberry pi and it worked great. The drivers have been used to control motors and LEDs (they are PWM-based, after all) and have worked beautifully. There is a bit of build quality questionable on some of them, so I think QC is lacking. That said, all of them appear to work fine. A couple of complaints I have are with the 5v DC regulator and the 6. 5v AC Using microprocessors to drive motors is a common application of these types of devices The Raspberry Pi (or similar microcontroller) can supply power to the micro-controllers using their 5V output. This page controls. While that works just fine, the regulator gets very warm regardless of the amount of current it has to Unless you can confirm it, I suspect that the 5V regulator isn't a switching regulator, and that it is just burning off the voltage difference between your supply and the In fact, considering that the whole board itself is a form of switching regulator (PWM), this is an odd design decision. As I said, however, I overlooked it due to the reliability of these. They can be placed in unconditioned spaces without experiencing overheating issues (their heat is scorching at times, but they keep running). I would recommend it for all hobbyists and those looking for small electronic projects (only be careful of the 5v output though).

The need was to use it to drive a stepper motor in single steps as well as "continuously. " The stepper will not perform microstepping (which I am not looking for) but its enable inputs allow it to be PWM controlled to limit the duty cycle of the magnetic field, greatly reducing heating and noise from the motor. Neither the heatsink nor the motor will shut off automatically when the stepper isn't in use, but you can do that with software (which is what I do). The NEMA 23 stepper barely heats up the heatsink at all. Anyway, I am using this device as part of a water treatment system to take care of my outside water connections (hoses and sprinklers) with polyphosphate to reduce iron absorption. We use it whenever we use outside water and it has remained a crucial part of the system for more than nine months. I would purchase it again because of its value and the limitations can be easily overcome with the help of some.

These can be bought elsewhere for a cheaper price. Design of this circuit is interesting to me In addition, there is the option of hooking up PWM to the pins so you can control the speed of the motor as well. *The motor has not been used for stepper driving 2 dc motors can be driven via this. You can use this module in so many different ways with so many different controllers that there are tons of resources available.

The nema 17 I had to use had a problem. It is an exceptional group of drivers. It was pulling a bit over 2 amps at times when some of the nema 17 stepper motors were in use. The two-amp drivers I have are rated at eight amps each but are not rated I briefly loaded them (I did not That is not a good idea) and the fries were not fried. As for the heat sinks, I had them in an area where there was minimal airflow There was some cooling, and that might have I would say that packaging was okay and that there was a quick turnaround (next The next time I need them, I will purchase them again. The fact is that I may even consider buying these specific drivers when I only need one amplifier. It is important to know that these heat sinks get extremely hot when heavy loads are applied.

They are easy to use, but they are sensitive to RF fields back at the control box. You should make sure the power rail is solid before driving an inductive load. A few small caps on the driven side can also reduce noise. In the chip data sheet, it is noted that 30v @ 100 uS will fry the device. Periodic 10 uS pulses (1 second each) will also fry it.
