SD/MMC Socket

SD cards are all over the place and they\'re great for storing large amounts of data. Why not take advantage by adding an SD socket to your next data heavy project. We use it on a whole bunch of our boards! The SD/MMC ( Secure Digital Disk / Multi Media Cards) cards use a very simple SPI serial bus as well as a 4-bit proprietary bus.
