I have done a bunch of googling and have a better understanding of
Odroid's choice of 1.8V UART and the basic unavailability of units at
this voltage. Just looking for a CP2104 does not cut it, as they still
manage to use 3.3V...
So I will just order the one from AmerOdroid. If I get another board, I
will see about just getting the cable so I can move the converter
between boards if needed.
Thanks
