We are still looking for more insights about this board, have You had chance to test some m/2 devices? how they work and is that stable enough?
What about power?
Someone asked about differential pair, is that a problem like with USB?
@jbutler You can just drop @semi file to any good PCB maker and they will produce and assembly everything for You. Jlcpcb is charing about $55 for 5x ready to use boards. Of course You can solder that Yourself and get bare boards for about $8 + shipping. The only thing that You need to pay attention is board thickness - it have to be 0.8mm.
