I cant drag and drop it into my circuit diagram?
What do I do wrong?

You need to download the .fzpz file and then do a file->open of the .fzpz file in Fritzing. The part should then appear in your mine parts bin and can be dragged in to your sketch from there.

thanx for the parts L298N

Thanks, it’s a great part!

As @Navrug mentioned, it would be useful to get the schematics too. I tried to directly edit its SVG or replace it with the one from:

but with no luck… :roll_eyes:

If you have a url for the board (a quick google search doesn’t find one) which has the mechanical dimensions and the pinout I’ll have a look at creating schematic and pcb (despite the claim “all working” pcb and schematic are both broken in the part above.)

Thank you!!! I’ve already found the pinout, but it’s quite difficult to find the datasheet with measures… I’ll keep trying! :wink:

Edit: @vanepp, I could have found it.

The linked data sheet includes outer dimensions for the board, but to create an accurate part the offsets to the connections is also needed.

That said, this is a “board” so it does not really have a PCB footprint beyond the mounting holes, so the pdf would be enough to create a usable part file.

OK here is an improved part with schematic and a somewhat odd pcb. Since a pcb won’t really fit this, pcb here has the outline of the board (which someone with a board needs to check for accuracy!) which as @microMerlin said is really only the mounting holes, but has a 6 pin header which you can install and run wires to the appropriate pins on the module.

Thank you for this part.

Hello…I’m using the l298n motor driver for my sensor based car the sensor is working but the motor is not rotating when I check the voltage at out1 and out2 it is zero then I had used to power source one connected Arduino and another to l298 still not working.

Check that you have the enable pins connected to +5V either by installing the jumpers between ENA and 5V (just above it) and ENB and 5V on the other end or that you are driving them from the micro with a high level. If they are low the motor won’t run. Also check the L298N ground is connected to the Arduino ground (if not, none of the signals will be driven!)

FMotorDriver

Pls Help me find this componen, i need this type of fan motor driver

22

We would need a web site for what you want. I’d guess it is probably this

but the site for what you have would be needed to find or make a part.

That’s an awesome H-Bridge! :sunglasses:

24

hi peter,
is this h-bridge 100% functional on all 13(!) connections?

so long
pc

25

Assuming you are referring to the l298n part there are 17 connections and they are all functional.

Peter

26

super ! … 17? (but with jumpers)

27

Yes, both the 5V enable and the two 5V power pullups are intended to be jumpers but need to be connectors in Fritzing.

Peter

well done !
pushbutton works, too …
thanks very much …

My students use this part a lot and I would like to put it as a core part. However, to keep cleaning the core parts, I think there are necessary a couple of small improvements.

  1. The label is currently “Mod”, but we agreed to use “A” for assembled boards like this one, see Suggestions for additional documentation
  2. The family is set to “L298N-motor-driver”, but maybe it is very specific. A similar core part, MD03A1, has “motor driver” as family, which is the opposite end (very unspecific). I suggest changing both of them to “H-bridge motor driver”.
  3. Change the variant from “variant 1” to “L298-Module”
  4. The pins in the PCB are outside the silkscreen. Is this correct?
  5. The description has an excessive return of carriages between the different paragraphs.

Thoughts?

If we make these changes, do we need to obsolete the parts?
