First excuse my bad english, translation has helped me. I wanted to check with Arduino, whether there is the possibility to create a similar board the Banana PI R1 router. However, I would like to 5 ports used as well there, but: 1: WAN 2: LAN & WLAN 3: multi-media devices (TV, Soundbar, Entertain Reciever, etc.) 4: Development, Test, very open unsecured devices precisely 5: NAS, backup etc. Port 3-5 so variable adjustable usable, also possible by software 3-5 to add LAN. Furthermore, should 2 SD cards, memory media to be present in order to integrate a RAID 1 by software or hardware. Cool would certainly also when multiple storage media, for example, would bring up on a Raid 5, Optional design. at least 1 USB port. I am no electronics and no high-level programmer, but I am not quite inexperienced in open source code and configurations.
Should little money and cost / be easy to learn for domestic use Adjustable.
