ZDnet had this article on this tiny successor (cousin?) to the Raspberry PI.
I couldn't help but wonder how it could be interfaced to the M100 to
enhance the M100s capabilities. Even if the M10x/200 ended up only being
a terminal into the device. I picture a small (3d printed?) plastic box
the width of the M10x either along the back side of the bottom, or just
along the back side, plugged into the M10x's ports, (especially if along
the back side), and possibly with a slide-out/flip-up (or
slide-out-then-flip-up?) 4.5" screen.
Control would still be through the M10x, but you'd have access to the
capabilities of the little computer.
(this does make me once again wish I could find a source for a modern
screen with dimensions close to the M10x's. )
