USB and 3.5mm Audio Combo Card

[MJ1]

So, I ask, how do I go about learning how to design circuit boards so I can make this expansion card a reality? Or does anyone know of a similar project that I didn’t manage to find? And no, I’m not buying any more dongles to fix this problem, I’ve had enough of dongles, even if it means I’m going to spend more money designing such a thing.

For learning PCB design, honestly, just youtube is enough to get started. I’d recommend KiCad. It’s free, open source, and not limited like free versions of commercial software can be.

I haven’t run into anyone creating a similar audio + usb project. Just some people saying they’d like such a card. There are projects such as dual USB-C port, dual USB-A, dongle + USB-A, dongle hider, etc. In varying states of completeness.

The dongle + USB-A card project might be a useful starting place for building the card you want. As it already contains a small usb hub chip, usb-c port, usb-a port. You can rearrange things, then add the audio components. I do believe the design is open source.

DongleHider+ - Multiple dongles and a normal USB A socket

I’ve finished my first Framework-focussed hardware project: The DongleHider+! It’s an expansion card that acts like a normal USB A expansion card, but can hide up to 2-3 dongles inside at the same time! You can find all information on the project’s GitHub repo or the Mastodon thread for a more behind-the-scenes look.
