Hi @MarSch 
all mentioned Jetson platforms are supported and behave the same with 
(64 Bit ARM)
I should mention that an internet connection is needed for the setup to install all necessary components. Otherise you will need to install some fonts manually afterwards, as described here.
There are still some limitations though. But they are Linux specific and have nothing to do with the Jetson platform. Not all tools are available under Linux. Have a look at the API Guide for more information.
