Chip on board on board on board Image
This was much more painful than I expected it to be to assemble... Image
#ftdi chips are out of stock everywhere. I have a couple ft2232h breakout boards that I could salvage from but they were qfp instead of the qfn I had designed with. Thus the COBOBOB #soldering struggle
Boards from @oshpark Image
Bonus jankyness:
I got the oscillator freq wrong (16MHz instead of 12MHz), luckily the breakout board had a 'spare' crystal.
The ftdi chip shows up on usb now! Image
