I'm not sure I'd buy that. Read the comments: Not suitable as master.
Range about 5m. I don't see any approvals (if you care) or technical
datasheet. Bluetooth also sounds like far too much hassle than it's
worth.

May I suggest these instead:

About $13 a pop incl pp and a far more solid appearance.

Not from dealextreme. The pictures look fine, if that's what you're
getting. Is it a 100% clone? Because if not, you'd want the layout files
and a decent schematic, which I don't see there. Preprogrammed with
bootloader if you don't have the gear for that? I'd rather buy from
nicegear.

But in general you're on the right track. It looks pretty daft to etch a
board if one can just buy an uno/nano/whatever this month's minimalistic
solution is.
