[RTTY] Genuine FTDI (Re: Programming an Arduino for TinyFSK, revised

[Peter Laws]

I'm amazed I still have this in my mailbox - thought I would have to
do some ugly cut/paste from the contesting.com archive.

Following the Sainsmart.com link takes me to an Arduino Nano clone
and when I looked that up on Amazon (where it's a buck cheaper!) the
reviews are all about how some instances of these boards have
counterfeit FTDI chips.  Since it's all about the UART, I'd rather not
have to work around that issue on top of what I'm already "working
around" (that being the lack of RS-232 port on my NUC :-))

Any advice for getting one that has a genuine FTDI chip?

Peter
