(TECH) Expansion Pack????

Can someone do a tutorial, (preferably video like YouTube), on setting up the expansion pack pieces??

I got one with my RePhone Create kit, and so far I’ve been able to play with the little LED matrix board, (although I’m not sure how to implement uses for it). I’ve also used the Basic Sensors board which works great displaying the X-Y-Z axis, ambient temperature and the amount of light sensed by the board, (in “lux” values).

My question is how to make the GPS board work. I’ve hooked it up, but I don’t see any values displayed on the screen, nor do I see a way to access it on the phone. Is this something that requires the use of the Duino board, and if so is there some code written to upload to this board for more uses?

Thanks in advance for anyone who can answer these questions.
