[Sticky] USB-C Microphone (official topic)

@avieatrix It's ready but the cost of parts from China (due to political problems) has made it quite costly.

3.5 is fully functional but as with any "beta" there are things I could have done better, there's also the question of if I should do a version without the CM108B (which is the "USB bridge" even though it's sold as an A/D).

@imp_inventor and I have been discussing to see what else would be useful and if you have any "requests" provided they're achievable, I'll include them.

I don't know the price estimate currently, but if it's beating an equivalent consumer product I still think that's a good deal. 

I saw you mentioned build instructions to go along with the BOM/files posted earlier on this page, but I wasn't able to find them when skimming through previous pages. Are those present and up to date? Because I might start adding parts up to see if I can order stuff soon if so.

This has everything you need - including some of my sweary remarks at myself 😉

@imp_inventor has been through the process more recently than I have so he's more aware of the "OUCH!" when you step on a rake - primariliy that you MUST use the right board stackup. Get that bit wrong and it's a virtual certainty that it won't work. Ever. And there aren't many recoverable parts, those that are are LSI and often very, very small indeed. That's a lot of dough and they (JLC's engineers, who are superb and very helpful) won't pick up.

I'm around most days if you need anything. I'm just neck deep in something that should have taken me about a week - is about, ooooo say, three months down at this stage.

Yeah, I can answer some questions if you have them but I'm still relatively new to this, so I don't know how much help I'll be. The furthest I've gotten on this project is the checkout (a point which I've reached about 4 times by now, each time with a slightly different tag), and the cost to build it and ship it to me would be nearly $200, if I remember correctly. It might have been $170.

This is what kills it right now for many of us and there's no way around it - even sending out the "gift" boards for beta test... NOOOOPE!
