Are you sure you want to do this? I suspect getting good quality sound from
those would be rather hard.
I think it should be OK (it's 1MSPS 12-bit) and it doesn't matter
anyway, we're talking about a cheap entry-level device here. If you want
good sound quality, use a M1.
* Two USB ports. If the transceivers are expensive, consider using
resistors instead. (This hack worked for me, even though I'm pretty sure
it's not USB compliant)
Best would be if the connectors would be OTG compatible.
Who will write software and gateware to take advantage of OTG features?
OTG receptacles are not directly compatible with keyboards, mice, and
MIDI devices, so there must be a clear advantage in OTG to compensate.
* That's all for the PCB! No Ethernet, DMX, etc. Hopefully we'll have
MIDI over USB support.
No ethernet is in my opinion a killer.
I'd also prefer Ethernet, but the #1 priority is to make the device cheap.
