My tiny computer has arrived early. Raspberry Pi3 model B. I then can start installing operating system, while i waiting for the other componentes to arrive. I think i will try NOOBS for beginner - Raspberry Pi OS – Raspberry Pi
Its easy and user friendly.
Edit: For those who dont want to mess around with features and so on with the Raspberry and is only aimed for the Navio extension, they could load preconfigured Raspbian from Emlid here - https://docs.emlid.com/navio2/common/ardupilot/configuring-raspberry-pi/
Some unpacking pictures
