Not over kill at all.   It is worth paying a few $$ not to have to
design a PCB.  Worse then that is that most will take shortcuts and
design it so that you need a sppepcial IC programmer to program the
PIC.  Thee $20 development boards allow you to download the firmware
over USB so users can do it themselves.

I'm looking at this pair of boards:

Ethernet and and SD card slot might seem overkill too.  But I want to
track performance, read out the phase difference over time and so one.
 So I want to be able to connect a desktop computer and a USB cable is
to short.  Ethernet will let me check from work or with my phone.
the SD card can be used to log data.   Likely hold a two years of data
on a 8GB card.

I want to try and apply the saw tooth correction from the GPS.  For
that I will need a uP that cad read data from the Thunderbolt's or the
Oncore's serial port.

One important thing.  It would be good if the software where easy to
modify be most "normal" people.  My hope is that if it is easy enough
then several people will and they will share their work.   The Arduino
is very east to program.
