Shield Pins

• A4..A5 : DS1307 RTC I2C data lines.
• D9 : Optional SD card detect.
• D10 : Chip Select (CS) - A logic one (high) on this pin will enable the SD card for reading or writing. A logic zero will disable the SD card. An optional breakable link is provided on the board which can be cut and a jumper soldered in its place. This is very useful if you have multiple shields with SD cards sharing the same CS line.
• D11 : SD Card Data In (DI)
• D12 : SD Card Data Out (DO)
• D13 : SD Card Clock
