Thank you, that looks promising. 5 + 10 days is a bit though. Might be worth it to just wait 30 days in that case

I am super sorry for being such a noob, but can be used to socket the board? And if yes: Do I solder the ones with pins only on one side to the pcb and the other ones to stick into the holes and solder to the nice!nano?

Thank you! It seems I might be able to just start the build process. Is it easy to install the battery later? I would assume I might need to remove the nice!nano and reinstall it? Would I then need to desolder?
