Lightning fast shipping on this one, overseas. Great little product, good quality board. As for documentation you can find all that you need on the creator's website and also on-line from the chip manufacturer. No headaches whatsoever, on W7
Bought one of these to test some custom drivers I wrote for the chipset, the board works great. Very fast shipping as well, I was expecting to wait a while but the board arrived within a day or two of my ordering it.
