Connectivity to Raspberry devices

Hi there!
RockPi X seems to have high potential to get a good alternative to RasPi. Thank´s to the developers!
Maybe I will fit it into my projects…
But I have a few questions concerning that device:
Is it possible to use the original 7" Touchscreen from Raspberry?
Is it possible to use the camera module?
Can I use RasPis USV-Shield?
For I didn´t find this specifications:
What is the storage temperature of RockPi X?
What about ambient operating temperature?

Thank you for answering my questions.
Best Regards
Georg
