Digispark ds1307 real time clock shield

I bought this kit with the hopes of using it as a rtc on a raspberry pi. I haven't been able to find anything yet in the way of a schematic for the kit or for the pin-outs on the digispark.
Has anyone done this and if so can you give me some pointers?
Thank you.

Every product page on digistump.com has a "Resources" tab with schematics and all source files - that should be all you need. Short version is P0 is SDA, P2 is SCK, for the raspi put 3.3v on 5V pin and connect GND to GND

I got the digispark and the real time clock shield too. I was also thinking of getting it to work on my rpi. First i would like to know that it is working. I got blink to work after i changed pin 13 to 1. Also played with something that printed a string back to the arduino interface. Is there a sketch that you can set the time and have it display back to the arduino interface or is there a monitor it will print to. Im on a mac. If you get a sketch working on your pi please post it. If i get one together i will post mine. Thanks. R
