Supercard Lite is a device that allows you to use a Micro SD card on your NDS Lite. It will allow you to run a variety of software, watch movie, E-book, music and photo albums.
The size of the Supercard Lite is smaller, to fit better your NDS Lite. You don't need to plug out the Supercard Lite from the GBA slot to remove the Micro SD card.

You will find in our Miscellaneous section compatible SD cards for the Supercard.
