Is the ecosytem poster under CC-SA License?

I’m wondering whether the Ecosystem Diagram poster is under the same CC-SA license as the hardware or not?

I would like to have a poster printed, but I know I will be asked if I have the rights to do so.

Thank you


In case it makes a difference, we want it for reference on our wall only, so it’d fall under CC-NC-SA if you’re concerned about commercial distribution.
