Improved Micro:bit part
Edge connectors in Fritzing are complex. While there isn’t a specific part for the edge connector at the moment it would be easy enough to convert the MicroBit part to just the edge connector if desired (pcb is already there, just bb and schematic need to change). I just uploaded a newer version of the MicroBit part and there is a howto on how to make edge connector parts in Fritzing in the howtos section of the forum (although it assumes a lot of knowledge or parts creation). If you are aiming at a Microbit, I’d suggest just using this part (the edge connector is extra strange because if internal connections for the Microbit), if you need just the edge connector for something else I can make a part that is only the edge connector easily enough.

Since you can in real life it seemed best if you could in Fritzing too 
. If you find other pads that should be in but aren’t post and I’ll add them. There are some odd pads around the board that don’t seem to be documented.

35 New & Edited Parts | #2
You need python3 either native (which I haven’t tried, but there are native Windows versions available), you would also need to load the lxml package which won’t be installed by default or as I do, by running cygwin (whch gives you a linux emulation on Windows) with the python3 package and python3 lxml loaded (neither load by default). I guess as part of the new revision I should figure out and document how to install on all OSes but I haven’t done so yet.

Microbit Edge Connecter. Help wanted by creating part
Just saw this post after replying in the MicroBit thread. The top block looks to be the edge connector itself, but I’m unclear on what the headers are meant to do. It looks like the middle set might be for .1 jumpers (or two connections to each MicroBit pin). It isn’t clear to me what the 3 sets of headers on the bottom do though. The .fzz file in the MicroBit thread is a breakout board that uses the Microbit part to do something similar to what is done here. It has mounting holes for the board and holes to allow the Microbit to be bolted in with plastic strips so it can’t fall out or be removed without tools. If the form factor doesn’t suit I can change it easily enough (such as if your mounting holes need to be in a specific place for something). Here is an image of the breakout board that I have cut as boards:
As noted the top section of the silkscreen is truncated by the board edge and doesn’t appear on the board. As noted the 4 M2 holes beside the MicroBit secure a plastic square beam bought from Ebay and cut down to hold the Microbit in place so it can’t vibrate out of the socket if used in a robot. You (or I) can modify the fzz file to add more connectors if you need them, the MicroBit part itself shouldn’t need changes and fits the listed Adafruit connector (I expect it will fit any MicroBit connector, but I have only tried the Adafruit ones). You should be able to add a 21 pin header .1 outwards from the current connectors to the socket via the fzz and either connect them with jumpers or put a trace between them depending on what is intended (you may need to change the position of the text though, but that can be done in the sketch). Then add and connect the extra headers in the jpeg with standard header parrs in the sketch and connect them as desired. If you need a narrower PCB, you can modify the sketch. The part ends at the M2 screw holes and so is pretty much the minimum space needed for the edge connector. You can move the board edge down as far as the pads of the edge connectors and the holes and silkscreen should be truncated as outside the board boundary (although I haven’t tried that).

Microbit Edge Connecter. Help wanted by creating part
Hi Peter
When the thick orange lines to GND and 3V3 are erased and P19 and 20 is changed to GND, it’s what I need. Pin 19 and 20 are not being used. Also the GND on the image you uploaded is not on the Microbit. Just look at the image I uploaded.
If you could do that I would be really grateful. Time is ticking. My course must be finished by monday.

How to find the danger shield
Hi,
I just wanted to ask where we can find the danger shield composant. I found a lot of shields but not that particular one.
Thank you in advance

How to find the danger shield
Which danger shield? There is a retired sparkfun one (which may be in the Sparkfun Fritzing repo although google did not find it) and one from Seeed studio, which appears to be still being sold but there may be others as well. A google search for “frtizing part danger shield” doesn’t turn up any parts though so someone would likely need to make a Fritzing part given the data on the shield.

Microbit Edge Connecter. Help wanted by creating part
I’m still unclear on what you need although a modification should only take a couple of hours once I figure out what you want. The thick lines are there to provide low resistance for the power lines. A number of the MicroBit pins use 4 pins on the edge connector as the part shows. The part as it stands correctly connects to all the pins on the Microbit (I have a couple and have tested it). I think what you want is to move the ground pin to where 19 is now, and delete pins 19 and 20 (although they are on the MicroBit and I would suggest leaving them perhaps moved to to after the ground. This can also be done with the current part by just adding the connectors you want and connecting them to the pins on the current part. The downside to that is that there will be an extra line of pads if space is an issue.

Ah! This explains what you need. I was looking at pcb thinking you wanted to make boards, but what you need is a breakout board showing in breadboard rather than the MicroBit. I can create a part with the breakout pinout as shown in a few hours I expect. Do you want the MicroBit attached to the breakout, or just the header connectors as shown above?

Yes I saw that, they also have a schematic somewhere. I’m not sure I have anything that will read dxf files though. At the moment the lazy bet is to have someone that has one tell me if anything is missing

OK while this is lightly tested and not a complete part, I think it will do what you want. The only pins that are active are the one row by the numbers. The row above that should probably be bused to the active row but I didn’t do that and all the other pins are cosmetic. However if you load this part in to a sketch and connect it as the jpg above in breadboard it will reflect correctly in to schematic and pcb.

the new part looks like this:
as you see some of the unused pins are showing up in red under the edge connector, but that won’t hurt anything.

Don’t know how useful these files are but, not clear on what’s wanted (and currently I haven’t much free time ).
Opened the DXF and STEP files and exported as .PNG.
The DXF from the ref site should open in Inkscape.
Three files ( .PNG) below are:

Thanks, I hadn’t thought of Inkscape. It loads but isn’t correct. The pads are in the wrong place mine is identical to yours above) . The copper layers haven’t been rotated somehow. The wireless module and the connectors at the top should both be rotated 90 degrees. Perhaps I’ll poke at the import routine and see if there is something I can do because that would be useful if it worked correctly. I see Infiniview will also open it (but needs a plug in I don’ t currently have). FreeCad opens it correctly but won’t export it as an svg. Sigh! So many incompatible tools
Edit: the importer says it has limited support for blocks and that I should use “explode block” first (which would require something that understood blocks of course), so I wonder if that is the issue. Don’t seem to be any obvious controls in the importer.

Improved Micro:bit part
Hi Peter
Thank you very much! Don’t know if you live in Belgium, but if you would live in the neighborhood I would by you a beer! 
If it aint to much troubles you may change the color brown to light gray (like the breadboard) and the text and pins black. But only if it’s not to much troubles. Or can I change it myself? How? In Inkscape?

Need for TP5000 shield fritzing part
Hello,
For my project I use some shields and modules. All but one is available in fritzing, can some one help me to create this part? It is TP5000 LiFePo4 charging shield.
An easyeda version of this shield can be found here: https://easyeda.com/module/TP5000_SHIELD-19bea625e30344b7a52efa0b8a96795b
Regards,
