Makeblock Me Orion with lego nxt multiplexer

#1

Is this multiplexer https://www.hitechnic.com/cgi-bin/commerce.cgi?preadd=action&key=NSX2020 compatible with the Makeblock Me Orion?

#2

I don’t see how it is compatible with the Arduino family. I would hazard a guess that it would be very difficult to get them to work together.

#3

what about this LegoNXT-Arduino shield?
