Need the LILYGO® T-SIM7600E/G-H ESP32 Module Please

[rehbeinjm]

Hi all,

Does anyone have the “LILYGO® T-SIM7600E/G-H ESP32 Module 18560 Battery Holder Solar Charge Development Board” fritzing file? Already looked at the SIM700G in this forum, however, the pins are slightly different and I’m having a hard time getting to grips with Inkscape. I’ll add the pin out below.

Thank you!

T-SIM7600E/G-H

This part should do what you want.

edit: Sep 17 2023 a post below indicates that I screwed up and added two pins that shouldn’t be there. If you have downloaded this part before the above data please download the new version!

Thank you very much Peter!!

I found 2 extra GPIOs in Peter’s Fritzing part: GPIOs 35 and 36.
I’ve corrected this in the following part:
LILYGO-TTGO-TSIM7600E_revised.fzpz (79.2 KB)

This is my first Fritzing part and post on this forum .
I found this youtube playlist really helpful for beginners like me who just wanna make or edit a part to put together a quick schematic or pcb: Fritzing Tutorial

Oh and thanks to peter who did all the hard work in making the part.
Would also love feedback if I’ve made any errors.

Good catch! While I appreciate you trying to fix it your self, in this case it would have been better to tell me about the problem so I could (as I have) fix it and replace the original part. That avoids having a wrong part floating around which is undesirable. Part making unfortunately is complex and there are no easy solutions I know of. Everything I did here is covered in this tutorial set:

Part creation howto part 1 breadboard and pcb

Someone in this forum post requested help to fix up a part. So while doing that I decided to record what I needed to do in order to fix the part to provide a tutorial to create new / fix broken parts. If you start from the Tarjeta S4A EDU.fzpz file posted in the above thread, you should be able to recreate my improved part posted in the same thread. I started by loading the original part in to Fritzing, that indicates breadboard is (at first look anyway) pretty good, but schematic and pcb are…

I think the video tutorials may be Old_grey’s set which are also good. That said, yes there are errors in your part. The first thing I did was run your part through FritzingCheckPart.py which reports the following errors:

This is a through hole part as both copper0 and copper1 views are present.
If you wanted a smd part remove the copper0 definition from line 43

many of them are harmless, but the lack of a layerId in schematic means the schematic will not export as an image. The lack of terminalIds in schematic causes this:

as well as the 0.05in offset from the grid (Fritzing decided to align on a connector without a terminalId so the pin aligns in the center of the line rather than the end.) Your part is on the right and my corrected part on the left here. Otherwise all looks fine. The label value should be A (indicating assembly) rather than ESP32 as well. We are slowly working on getting some standards together for parts but it is likely to be a while yet.
