I should point out that the TFT module has only 34 pins. I’m a beginner user of the Fritzing program. I’ve started learning it but haven’t gotten to the point of drawing and configuring modules yet. I promise I’ll get there eventually. For now, I’d like to know if there’s a module like this available in Fritzing. Thanks in advance.
Peter
Hello,
Is it about this part:
Regards, Harald!
No, that’s not the right module; the one you showed has 40 pins and uses a different type of chip.
Peter
Can you send me the link to the correct module?
Regards, Harald!
Inch TFT LCD Touch Screen Module Display Ultra HD 320X240 ILI9341 for 3.2 ''3 | eBay.de.
This is where I bought it
Peter
You say yours has a different chip. Does it have this one installed:
IC SSD1289
or actually the ILI9341?
But that isn’t really so critical for the Fritzing part.
In the linked datasheet, it’s more about the dimensions and the number of pins. Could you please check whether that’s exactly the case for the module you bought?
Regards, Harald!
Well, I looked again. Unfortunately, I don’t have a datasheet for this 34-pin display.
Do the outer dimensions at least match what I sent you? Could you send a photo of the pin side?
I’ll definitely keep looking.
Regards, Harald!
I quickly sketched this by hand; I’m using the display successfully in a program with the XPT2046_Touch library—I just need it to create documentation for the completed project. I tried to modify an existing 40-pin display, but something isn’t working. I modified the SVGs, saved them, and then restarted FZPZ. Some pins aren’t defined somewhere, but I made the changes. For now, I’ve created a diagram like the one in the picture.
I drew the picture quickly by hand
Peter
With this configuration, it works correctly and has a fast response time; it doesn’t freeze when receiving multiple signals, as we experienced with SPI displays.
Peter
Ok,
that looks good; I’d say those are exactly the dimensions I have as well. I’ll try a first attempt by Wednesday (or Tuesday evening). I’ll adapt the display with the 40 pins and hope that’s okay.
Regards, Harald!
I’ve got a first pass done. For now, this is just the breadboard view. I left out the labels because they’re also on the back of the original part.
Does this work like this…
I don’t know if I’ll get around to it tomorrow, but definitely on Tuesday.
Thank you so much for your involvement.
Peter
So, now I already have something for you to test. If you or someone else finds any errors, we might be able to fix them tomorrow.
Here’s the part:
3_2_Zoll_Touch_Screen.fzpz (11.5 KB)
I created a test file and tested the autorouting. It worked. Here’s the example:

Regards, Harald!
I really appreciate your help. I’ve replaced the module in the diagram as you suggested, but I think it will take some time to test it—I don’t really have time during the week to work on the project.
Best regards, Peter
Great that the import worked for now. I will continue to look for errors.
wroom ESP32” module that’s actually incomplete. I’m interested in the schematic and the PCB. I’ll post what I’m currently using.

Sincerely
Peter
P.S. I don’t want to seem pushy or rude, but that’s already asking too much, so I’ll accept a “no” for an answer.
For the schematic, there’s an extension in Inkscape. For the PCB, you might be able to use a different ESP with the same pinout. I’ll try to keep at it until the weekend.
Regards, Harald!
I just want to say that module exists in Fritzing. I’ll attach a photo with yours (it’s way too big) and the available ESP. I simply entered ESP32 in the search field.
Which version do you have?
Regards, Harald!
It’s me again. I took a look at the ESP32 from the parts library and, to my dismay, realized that I had modified it myself at some point. There is a version with fewer pins. I then bought one from AZ-Delivery. That seems to be the same as yours. I then simply cobbled mine together from the version with the fewer pins. But that was in an early phase; it’s certainly not free of design errors.
I’ll upload it for you anyway.
ESP-32 AZ-Delivery.fzpz (22.2 KB)
It definitely has errors, but I will revise it.
Now I’ll say a few words about the model; mine is the 30-pin version. In the latest architecture I attached, the pins marked with an asterisk are missing, so I have the 30-pin module. The photo from “NodeMCU-WROOM-ESP32_30pol.fzpz” fits perfectly, so the combination of the latest schematics with this *.fzpz file would be ideal for me.
With all my respect
Peter
