Hello,
I am working on a professional project involving the SeeedStudio Grove AHT20 (ref. 101990644), an I2C sensor for temperature and humidity.
I found the Fritzing part corresponding to the Adafruit AHT20, which is functional and very close electrically. However, this poses problems of readability in the schematic, especially for fellow developers who are not familiar with electronics and rely heavily on visuals to understand wiring.
Would it be possible to add a visually consistent “Grove AHT20” version with the other Grove modules available in Fritzing?
This would greatly facilitate the integration of the component into drawings intended for technical but not electronic profiles.
Thank you for your work and for the Fritzing tool, which remains a reference to document this type of assembly !
There are eagle files for the part I will post a part in a while.
Peter
Perfect thank you for your responsiveness !
I did not know that I could use eagle files to create components in fritzing, I would try this method the next time I need a component, thanks for the information

This part should do what you want. Note the grove connector doesn’t appear in pcb and if you want the mounting holes (which are not drilled by default) you need to drag a pcb->hole part in to the sketch, place it over the hole in silkscreen and set the hole size appropriately.

It’s perfect for my use thanks again !

Well it requires installing Eagle2fritzing and building Fritzing from the source. It requires disk space to install Qt, Qc (Qt Creator), Fritzing source code and E2f. As well EAGLE is phasing out in June 2026, and after that month, the tools are obsolete — they won’t work (unless the developers change the code)
As well it assumes you are a parts making expert (it was written by and for the developers around 2016 who were part making experts) and is not at all easy to use. It is possible that it could be extended after Eagle dies in 2026, but may not be worth the effort as it is a complex task. It may turn out to be easier (if a little more work) to just make parts in the conventional way.

Actually yes and no. As far as I’ve tried, you can’t directly open an .brd, .sch, or .lbr with a double click — it will launch the launcher and will not open the file.
Our only hope is that @KjellM or the other developers update it before June 2026. I’ve also observed that Adafruit heavily uses E2f
There is no doubt it is useful. It generates an accurate board outline in breadboard and an accurate pad layout in pcb view, it just takes a lot of knowledge because of what it leaves out (assuming you know how to fill in the missing sections which in the general case isn’t true!) I think the use of Eagle is to convert older Eagle files to xml before processing them. There is a note in the source that that could be removed as the older files are rare now. I think (but don’t know for sure!) without that it would the xml ,brd files without needing Eagle. If that can be done easily it may be worth doing.

Well, thank you very much for your exchanges! I will simply take an interest in it without forcing if the task seems too complex. I could always try with a more conventional method, but I think I would propose a new topic in “parts help” when I would have difficulties to find a component.
I am a development student and this exchange has been constructive for me, thank you again!
