The Framework-16 Expansion Bay does not have a DisplayPort input. It’s PCIe, USB 2.0, a bunch of power pins, and some misc control signals. Framework has the Expansion Bay connector pinout on their github. Of course with PCIe you could create any kind of active Expansion Bay module that you’d like. There just is no DisplayPort input natively present that you could simply tap into.
I’ve seen people do that a lot, particularly relating to the drivetrain of the Chevrolet Volt car for some reason (and sometimes even arguing with me about what their source says when I directly quote the source).
In fairness to those people Chevrolet’s marketing did a really bad job of explaining the Volt’s drivetrain (if someone’s interested in a full explanation of that I’d be happy to share it, but otherwise I won’t type it up as it’s not related to Framework).
I don’t know if this is feasible from a software standup point. But maybe we could have a special input module with an NFC reader so that if a certain user wanted to login or access a special service/app they would have to tap the NFC module with their key. Either a keycard or a phone.
The creator of that LTE module is on the forum. And while he didn’t create a thread dedicated to his module, he does post about it in this thread, as well as answer questions
How about a wireless recharger pad using one or two input spacers? connecting a rolled copper wire seems relatively easy to make, you could recharge your smartphone battery and even a mouse with that technology, even though there still are few of those nowadays, there is also a chance for framework to make a mouse like that
There is also only 3.7mm of height available if I recall, with only a small section of extra space for electronics. Qi charger circuity is not the most compact. I don’t think you could fit the coil, required coil backer plate, and the qi circuity. Maybe if you do a tiny coil only suitable for charging a smart watch. Though, I must admit, a qi watch charger would be kind of neat to see, even if the usefulness would be limited.
