Hello!
Launchpad is an option if… you use another processor than Launchpad's CPU.
You can use Launcgpad as a programmer for another CPU of the F2x series.
Otherwise, you will be stuck with 128 bytes RAM and 2k flash.
And keep in mind that you cannot use all the RAM, you have to leave some
room for the stack.
If you interface a MSP430 and a GPS, I suppose you will need at least
one LCD to do something with the data, and possibly one SD card.
In this case, you will need 512 bytes for the SD card access. Then if you
want to implement a FAT, you will need a few hundreds bytes for data
and tables management.
Here is **broken link removed** with MSP430.
