Thanks all for the answers. @Jojopi, I think your right. @BigRedMailbox: Yes, I have a 40 pin GPIO header, its behind a rubber cap. I did find "RTC Pi Zero", but I'm unsure if that will fit. I could put the print in a case, so all components are shielded for touch. You have to solder the 40 pins connector to the print, but in the same time you could swap it for one with the contacts bend 90 degrees. @gordon77: I don't think its a good idea to open the pi and build it inside.
