Chris Albertson sent me a note pointing out that these GPS modules are 
just little "bricks" so to speak, and need a circuit board to work with 
them.  After doing some more searching on SparkFun, I found these links 
to some interface boards.  There may be others as well.





(PS - If you email me and don't get a quick response, don't be concerned.
I get about 300 emails per day from alternate energy mailing lists and
such.  I don't always see new messages very quickly.  If you need a
reply and have not heard from me in 1 - 2 weeks, send your message again.)
