Just FYI noy you can get the USB-C riser board for the wireless YDKB controller https://github.com/joric/usb-c/wiki#ydkb

A small update:
There are 4 PCB's currently being tested. So far everything is working perfectly (one HHKB JP user). I have one additional unit that I'm holding for a friend that also will be put in rotation and used for testing. For transparency: I sold the prototypes to people who have shown interest in the project for 50 usd + shipping as a symbolical sum and to cover a little bit of the expenses (thanks for support  :D ). I have no gauge yet what they would cost if we go to GB in the future.

I'm looking at replacing the USB-A connectors if I find a suitable alternative (SMD, USB-3 and readily available from a common supplier). The current one from wurth works good, but I find it a bit "flimsy" since the usb cable can be moved a bit side to side. Good but not perfect.

The current iteration of the PCB works as I have intended it to, I have tweaked the USB-A port placement a tiny bit in current files. The downside with the project is that components are pretty expensive and the design is a bit complex. It would be interesting to look into the possibilities of a cheaper version. Maybe with a cheaper controller with possibly built in USB-C mux (eying the Genesys Logic chips) and possibly switching to ganged power limiting (900mA in total, not per port) to reduce components and connectors from LCSC not wurth, but this would need prototyping, funds etc etc.

I will let the testers run the boards for a while to see if there is any issues that come up.
