After the problems I had with the last batch of boards, I went back to the drawing board.  Well, back to hackaday.io anyway, where I found #Business Card Gamepad, which I figured might be a solution to my USB Type-C receptacle woes.  I found the relevant drawing in the USB Type-C spec and drew it as a KiCad footprint, which I then used to make a new version of the board.  Since it has to be 0.6 mm thick now, I couldn't order this board from OSH Park, so I went to Dirty PCBs instead.  The quality is quite good; the boards aren't dirty at all.

I originally considered gluing on thin pieces of single-sided copper-clad FR4 to act as shield pads.  I tried this on one board and found that it made no positive difference to functionality or robustness.  Securing them well enough was difficult, and excess glue caused some problems.  So, I ultimately decided to leave them out.

The new board works just as well as the older board revisions, and is much easier to build because I only have one connector to solder now.  I just listed them on Tindie, at a reduced price due to the lower material cost.  Hopefully this will be the end of the PD Buddy Wye supply problems!

Those look really nice! Did you try with any other board thicknesses? Was it a snug fit?

  Are you sure? yes | no
