BOM & Part Sourcing
I will start by saying I have not reviewed your project. But with that said I have to agree with Peter in the use of a prebuilt MCU module. You could use an Arduino Pro mini 3.3v if you don't need USB for anything other than programming. You could use a Nano 5v as Peter mentioned if you need USB all the time. Or you could use a new Arduino Pro Micro 3.3v which is based on an Arduino Leonardo and has built in USB like the Nano but has the same small footprint as the Pro Mini. The pro mini can be purchased for $2 each with shipping if you can wait many months or a little more for decent shipping. The Pro Micro and Nano are both about the same price and not much more than the pro mini.
I would also suggest something like a ESP8266 if you only need a few pins as it is 3.3v which you want, Arduino IDE compatible and has built in Wifi (limited memory though). If you need more pins you could also use an ESP32 which has bluetooth and Wifi plus tons of GPIO's and is also 3.3v and Arduino IDE compatible. The Esp8266 is really low cost and the ESP32 is also a good price (under $6 from a few places even in the US), The draw back with the ESP modules is no built in USB but you do have Wifi and Bluetooth so no real need for USB.

Program dies when I try to do a file open
I don't get as far as trying to select a file.. A window pops up where I would select a file to load but before I can even look to find a file, a windows popup tells me that the fritzing program has stopped responding

Does Anybody as ever created a 4 Channels L298 H Bridge?

BOM & Part Sourcing
Hi guys, I'm aware of the benefits of prebuilt arduino compatible micro controllers, but this is not the point. I'm building an all in one board and I have my reasons why not to solder on a pro mini.
I was just asking advice on whether my schematic and BOM seemed ok, but no worries; I've gone ahead and ordered all the parts now anyway.

Do I need ground fill and if so how do I do it?
I've said this before but I'll say it again, I'm a novice.
Now, I've routed my PCB and I'm happy with the layout, but it's all just traces without copper fill. Do I need a ground fill? I've come to this as a complete beginner and I just don't know if a ground fill is needed or not. Any advice?

2 mal MINE-Sortimente
Hallo Old_Grey,
Ich weiß jetzt, wie man es am besten macht, damit man keine doppelten MINE-Sotimente bekommt.
Mein Tipp:
Keine Teile in das MINE-Sortiment ziehen. Dies lässt sich, weil es ein Standardsortiment ist, später schlechter importieren. Dann hat man schnell wieder 2 gleiche Sortimente!!
Einfacher ist folgendes: Man erstellt ein eigenes Sortiment. Darin zieht man sich seine gewünschten Teile aus dem bestehenden Fritzing-Sortimenten darein. Dann importiert man andere Teile in das eigene Sortiment. Anschließend exportiert man das Sortiment. Dann Fritzing schließen ohne speichern von Dateien!!!
Dann den Ordner C: \ Users \ username \ My files \ Fritzing löschen.
Fritzing starten und das eigene Sortiment importieren. Es wird automatisch ein Sortiment mit dem eigenem Namen angelegt und die Teile importiert.
Fertig.
Funktioniert perfekt.
Gruß

Then if you type l298 in to fritzing parts search window the various breakout boards and chips in the core parts will appear (there are 3 or 4 of them). If that doesn't suit you can google for something that suits your needs better.

Rectangle Load Cell/Weighting Sensor
A rectangle load cell or weighting sensor with four wires coming out: Red, white, black, and green. This is based on a load cell from Sourcingmap (5 kg).
It works well for the breadboard view, but is not a PCB part.

Program dies when I try to do a file open
The debug console show nothing useful. If I do not try to open a file, the rest of the program seems to work.

2 mal MINE-Sortimente
Win7 is fine, so it must be W10.

Hello Old_Grey,
I know now how to do it best, so that you do not get double MINE-Sotimente.
My advice:
Do not pull any parts into the MINE range. This can be imported badly because it is a standard assortment. Then you have quickly again 2 same assortments!
The following is easier: Create your own assortment. This is where you pull your desired parts from the existing Fritzing assortments. Then you import other parts into your own assortment. Then you export the assortment. Then close Fritzing without saving files !!!
Then delete the folder C: \ Users \ username \ My files \ Fritzing.
Start Fritzing and import your own assortment. An assortment with its own name is created automatically and the parts are imported.
Finished.
Works perfect.
greeting

Program dies when I try to do a file open
This is a weird one! A couple of weird suggestions: check the file manifest of the install zip file to make sure your av didn't quarantine a program. This failure is a Fritzing bug which will also occur if I screw up a filename in a new part (so the listed file name doesn't exist). I think the open fail exception doesn't get handled somewhere and frtizing hangs exactly as you describe (although only when I open the new part which isn't the case for you). The other out there suggestion is delete all the directories (the install, and the two user directories) then disable the network connection and do the install with no network connection. This will block the parts update from github, and if fritzing then works that would indicate a new parts update is what is causing your problem (likely because of a missing file). That would at least give us somewhere to look. Other than that I'm pretty much out of ideas!

How can I find Bipolar Junction Transistor (BJT)?
I am looking for BJTs. More specifically this BJT from STMICROELECTRONICS. Thanks for your help in advance.

Deleting connectors doesn't reset to the top
When you delete a connector in the Parts Editor/Connectors window the whole window scrolls back up to the top connector.
I had to delete 40 connectors on a Ard Mega, and when you get down the long list and you delete one, it jumps back to the top losing your place. There is a lot of scrolling between each one, so it would be good if it stayed where it was.

How can I find Bipolar Junction Transistor (BJT)?
A search for "power transistor" in frtizing parts search turns up pnp and npn power transistors in a TO220 case. The schematic is a single transistor rather than darlington though so if you want an accurate schematic you would need to create a custom part and modify the schematic svg to darlington. However a quick google search indicates there is a tip120 available in the adafruit fritzing library available on github as well which may have a correct schematic. I'd try their first as it indeed has the darlington schematic although it is pnp. If you need the npn it should be simple to modify that part to be npn (I can do it for you if you need it).

I'd expect editing the fpz file with a text editor to remove the offending connectors would be the easy way to do this. You don't even need to do the svgs (unless you need the visual evidence gone as well) as it they are gone from the fpz fritzing will ignore the terminals in the svg.

I'm no good at XML so I have to do everything graphically.
I had to remove them in the svg because I need the room to run tracks.

Hey Peter, Thanks a lot for your reply and my apology for the late respond. different time zones 
off course that would be a great help if you could make it for me. It will be even a bigger help if you could teach me how to do it myself too.

Where can i find (NodeMcu V3 esp8266 12-E) Module
Is anyone use this Module or Maybe for V2 , it's similar ,i only can find esp8266 E01 and esp8066 12E
thanks all

How can I find Bipolar Junction Transistor (BJT)?
Turns out I was looking at the schematic wrong, it is in fact npn now so the adafruit part should work as is. It is available for download from:
with load instructions at:
As to making your own parts, a couple of tutorials:
If you need the pnp version (looks to be Tip125 and up) what I would do is export a copy of the adafruit tip120 use 7zip to unzip the fzpz then use Inkscape to edit the schematic svg and change the direction of the arrow on both transistors. Then save the new svg (removing the px on font size that Inkscape adds) then edit the fpz file to change the metadata to indicate the new part is PNP rather than NPN and change the part number. Then use 7zip to rezip the part for import to Fritzing. I can do it quite a bit quicker than I can type it , but if you aren't familiar with the process and Inkscape it isn't necessarily as simple for you (although it is a good skill to aquire, it just takes some time to learn). If you in fact need a PNP feel free to try an make it and ask if you have problems. Always happy to help people making new parts.
