I’m testing a SD card data logger module ( JP Module ) that I bought from www.jianpingusa.com/jpmodule.html . It’s very easy to use and great for my GPS project.

There’s another one that I bought. It’s pretty cool. They even have a board for micro sd cards and can use the sdhc cards, so over 2gigs. They cost $32.
