Yes. And they are connected through a tiny ribbon cable to carry along the
I2C signals and 1.8V power.

We all know that there are two ideologies represented by the members of
the community. One wants to have a finger friendly keyboard on screen
and no additional hardware. The other one wants a physical keyboard and
always a full screen because it gives better tactile feedback and is more
reliable when typing fast.

Our idea is: why not serve both? So this is the solution for the second group...
