Krishna used the Bus Pirate to interface a MT3318 GPS receiver.
I have used the transparent UART mode of the Bus Pirate to directly access the serial data and send it to other third party softwares to show my location on google maps.

Wait a minute, can’t you do this with any USB-Serial adaptor? For that matter, many GPS receivers are USB already.
Sure, lots of ways to do USB->serial.
yep…
quite a lot of the adapters
but i am too lazy to buy one for 3.3v
seeing as BP had a 3.3v provision
i just thought it might be fun to try and get it working with the BP
Ah, I forgot about voltage compatibility issues…
