The Realtime Datalog & IO shield is a platform to interface various sensor and IO modules. It provides real-time clock and SD card interface for mass storage of sensor data.

Analog pins are brought out to the connectors on the shield. D3,D4 and D6 are used for the RTC. D5 (/CS), SCK,MISO,MOSI are used for the SD Card D10 is not actually used, but must be an OUTPUT and High during setup of the SPI interface.
