| If you look up in the [[http://www.interfacebus.com/Multi_Media_Card_Pinout_MMC.html|MMC card specification]], you'll find out that these are what the 7 pins are for. (SD/high speed cards may have extra pads, but that standard was added later because the existing standard was considered too slow for big megapixel cameras) | If you look up in the [[http://www.interfacebus.com/Multi_Media_Card_Pinout_MMC.html|MMC card specification]], you'll find out that these are what the 7 pins are for.

You can trace the wires to correllate the pins of the chip to the pins of the header and verify for your self that this breadboard is correct. \\ \\ **Exercise: Verify the pinout for this target board ** | The black mark on the PCB and header indicate pin #1.
