UARTS: Not sure which UARTs are "free" with that combo of I/O (some
boards may not actually use a serial port but may re-assign some GPIO
pins to a function other than that used for a UART). Also, technically,
I don't believe the GPSstix UARTs are really "TTL" level, as that
implies 5V. The proper term is probably "LVCMOS", and the console 
boards Wiki says they are 3.3V:

USB: The Expansions Wiki page (recently updated by the gumstix folk)
says the GPSstix USB is client only:
