Does anyone have Fritzing parts for these 7-segment LED displays:
4-digit: HS420561K
3-digit: HS420561K
2-digit: HX220561K
I had a go at making a 3-digit 7-segment part, using Inkscape. I created the images which looked OK in Inkscape, the PCB image is fine:
and the schematic vie in Inkscape looks OK:
But when I load the schematic into the Fritzing Parts Editor this is what I get:
Can anyone tell me where I went wrong in Inkscape when saving the schematic view? I did group everything before saving.
We can not tell what is wrong with the svg when what you posted was a png. If the forum will not accept the svg directly, rename to append .zip to the name. An initial guess is a problem with the units for the image file, or the font used for the text.
Sorry, here’s the SVG file.
I ran the svg through a part checker script we have. It reports several errors. Here is a summary, with the duplicates removed.

Removed px from font-size leaving 60
The font-size attribute should contain just a number, without any units. There are 46 cases of this, mostly with size 60, but a few with 50 or 59.«something». Just need to remove the “px” after the size values, though might was to change those 59.x values to 60.

Key -inkscape-font-specification
value 'Droid Sans, Normal' is invalid
Inkscape got too smart, and added an inkscape specific font specification that is not compatible with Fritzing. 11 cases. Just need to remove the “-inkscape-font-specification:‘Droid Sans, Normal’;” entries.

Apparant nested tspan which fritzing doesn't support
If your text doesn't appear in Fritzing this is probably why
Fritzing does not support tspan elements. 11 cases. Text content needs to be directly in a text element. Replace the whole tspan element with just the text that it contains. This could cause the text to move (if the tspan coordinates are not the same as text element), so need to check and adjust that afterwards.

Found a drawing element before a layerId (or no layerId)
You wrapped the content in a group, but did not add the “schematic” id to the group.
The checker tools automatically fixed the first 2 cases. I manually cleaned up the last 2. Here is the result. Give it a try, to see if the issues go away.
Thank you @microMerlin that was a real help, much appreciated. Are you able to share the part checker script, or is it freely available (I haven’t checked yet)?
Also, thank you to @Old_Grey watched the video and that too was very helpful.
I’ve not created parts before, and it is quite satisfying.
I have been finishing off both the 3-digit 7-segment LED as well as a 4-digit version. All appeared to be going well until I sent a PCB image to PDF and then the pads appear odd, although they look OK both in Inkscape and Fritzing! This is what the PDF image looks like:
I have attached the part.
FritzingCheckPart is a python script available in its own github repository.
What you attached to the previous command was only the xml part definition file, not the full part. The full part would be an fzpz file, which is a zip with the fzp plus the view svg files inside.
From the symptoms in that screenshot, I am guessing you hit one of the Fritzing bugs, where it does not handle some specific conditions in valid svg path elements. I did some work on that for Design Rules Check. This looks like it might be similar, but need the full part file to be able to check. I am not currently setup to do debug/trace on pdf export, but may be able to narrow down by manual adjustment to the problem path elements. As a check, to see some of the scope of the problem, what does it look like when exported to jpeg or svg? Or to gerber. Some of the code is common, some is different for those options.
@microMerlin sorry for attaching the wrong file. The attached should be the full part, both 3-digit & 4-digit, I created earlier. When generating Gerber files and viewing in an a Gerber viewer I see the same issue with the pads.
HS320561K.fzpz (16.6 KB) HS420561K.fzpz (17.8 KB)
You can’t use ellipse for pads in FZ - FZ won’t understand them -, so they have to be changed to circle.
Groups and group labels aren’t right, especially in the 3 digit. You might have to ungroup and regroup things, but all things that aren’t contact pins go into a group called silkscreen. And all contacts go into a group called copper0, which has to be grouped again and called copper1.
You can use the free Gerbv viewer to check if parts are going to be rendered correctly.
I ran the HS320561K part through FritzingCheckPart. That got a lot of complaints. Looking at the svg files, I found there were multiple layers of group in group in group … wrapped around whole file content, and blocks of graphics within files.
“copper1” groups exist in breadboard and icon images, as well as pcb. The pcb image has a copper0 group inside of copper1, implying through hole, but the copper0 group is empty. The copper elements all exist on only the one side (bottom) of the board. The fzp file information indicates that the connectors should be on both sides.
Loading the part into Frtizing, and examining the results, pin 6 connector is missing in all views. In pcb view, the expanded ellipse pad exists, but not the connector. I see a “connector0pad-4-4” ellipse, which is probably supposed to be that missing connector5 = pin6. If that is a “no connect” pin, it should exist, and be tagged as such, in at least breadboard and pcb views. The schematic view of the part is rather over sized. It should be more of symbolic view, instead of those drawn shapes for each segment. In breadboard view, the connector pins are bigger than they should be. I schematic view, the pins (lines) are not aligned to the standard 0.1 in spacing.
The fzp title element should be a description of the part, not the part number. The label should be prefix used to tag instances of the part (along with a sequential number). Something like “disp”, so multiple instances would become disp1, disp2, … Duplicating the part number in the variant is not needed. For this, variant does not need to exist. It would be used to identify variations that would otherwise have identical attributes.
The definition information says 300mil spacing. Breadboard looks like 400mil spacing (possibly from those px units). pcb view looks like 600mil spacing.
With both your original, and my modified version, exporting the pcb view looks good for jpg, png, pdf, but I see your glitch on the svg export. Examining the source and created path elements, I do not see anything specific that Fritzing should choke on, but the different structure says it dropped some segments of the path. Which would be a bug.
I used inkscape to ungroup those groups multiple times, deleted the empty copper group, then regrouped the pcb elements to get the non-silkscreen elements inside a copper0 group, which is inside of a copper1 group. After that, I ran FritzingCheckPart on the result. The full report after that is below, with the file paths truncated to shorten the lines. Here is a summary of what it says.
- the fzp file is supposed to have an attribute recording the Fritzing version number.
- the breadboard file is dimensioned in “px” units, which is not safe
- the fzp file has definitions for connector 0 through 4, 6 and 7, 9 through 12. 5 and 8 do not exist, and they should (do not HAVE to) be sequentially numbered
- that extra/bogus copper group in the breadboard svg shows up first, so this complains about expecting to find the breadboard id first
- there are connect«n»terminal id attributes specified for breadboard view connectors in the fzp file, but they do not exist in the svg
- the connector«n»pin elements in the pcb svg are ellipses, but Fritzing, especially gerber output, expects circles. Holes will be drilled only for circles.

Here is the part with the described adjustments. It is not correct yet. It only has the nested group and pcb copper 0 stuff cleaned up.
HS320561K-2.fzpz (18.1 KB)
I said the glitch is a bug. However similar structures work elsewhere, even the second row of pins in this part. So it should be possible to build those paths differently to avoid whatever is triggering the glitch.
I roughly did one pad in PCB to show you how the pad fault corrects if drawn correctly.
HS320561K-3.fzpz (15.9 KB)
I’m starting from scratch and starting on the schematic view. Using a 0.1 inch grid to ensure it’s correct, with a line stroke of 0.25 mm. I’m also going to use meaningful ids for each part in the xml structure to keep track and what is what. Going to do this carefully from now on.
What I had created before was a good learning ground.
I have this afternoon created this 2-digit 7-segment LED part. Thanks to @Old_Grey the pads now show in the PDF images as good. Thanks to @microMerlin for your help as well. I haven’t run the parts checker over this, as I haven’t got the environment setup to run that yet.
I will create the 3-digit and 4-digit variants of the 7-segment LED another day.

Below is the report from FritzingCheckPart on your new version. Summary and translation (where different from previous):
- “copper1 layer should be at the top”: in this case, “top” means outer group. You have the copper groups inside of the silkscreen group. There is also a some wrapper groups around silkscreen. In Inscape, ungroup 4 times, then select just the silkscreen rectangle, group that, and set the group id to silkscreen
- “Connector connector0terminal is in the fzp file but not the svg file” Need to either add those terminal id attributes to the breadboard svg, or remove them from the fzp.
- “Found a drawing element before a layerId (or no layerId)” probably from those groups outside of silkscreen
- “Connector connector10pin has no radius no hole will be generated” You put the connector«n»pin ids on the path elements. They need to be on the circles instead.
