Re: memory card sd-mmc

You will need to buy the socket(widely available from inter net store).
A 3.3 voltage source to power the card.
couple resistor for step up and down from the bus between microcontroller and the card.

after that you are good to send command in order to communicate with the card.

Any more information on the software . Please ask . I don't know what else you need.
