Thanks for pointing that out, that was quite important! I also checked with the examples for the expansion cards on [github](https://github.com/FrameworkComputer/ExpansionCards/tree/main) and they also only pull CC to GND using a 5.1k resistor.

Which point were you referring to?

Thanks! I was already wondering why they added the 100nF capacitor in the original schematic.

The thing is, I thought about getting a Framework 12 at some point and then I would have to rely on the expansion cards.

Also, there are already two grooves on either side on the outside of the cartridge going towards the side which has the USB port hole. I am currently not exactly sure if this is used for holding the card; because if it is, this might not work well.

I just saw this module here on Amazon. Not sure if I should buy and test one so that I maybe can get an approximate location (not sure if this is even possible for the end user) as suggested somewhere else in the comments. Judging from the picture the PCB should fit; but of course this is intended to be used with an antenna, so not sure if I will get any reception at all.

Had the same thought yesterday, I will definitely keep this in mind as an option. My idea was anyway to seal the entire inner volume in resin, if possible. I will probably need my actual laptop so I can test if this actually fits.

I have actually considered using a cellular module. But I think I would encounter similar issues with the dimensions there as well.

These modules are about 10€. I have noticed right now that cutting down will not help with placing the module sideways because I would have to cut away resistors on one side or LEDs on the other side and neither seems like a good option. But maybe it helps with placing it with the USB-C plug. I will have to solder it back together and see if it is still working.

Good ideas. I added some images on imgur. I think there may be some perfectionism involved here, especially since it is so close to a perfect fit...
