You might want to think a little more about which to get.  The Pi is OK and
will work fine but look at "BeagleBone Black".  It's a little nicer for
hardware hackers. Cost is $5 different.   You can read specs and the
respective forums.

One thing to watch out for is that all ARM boards run on 3.3 volts.  The
serial ports are 3.3 volts.  Don't connect a 5 volt signal and certainly
NOT a real RS232 level signal
