So i want to try and keep the 2.8" screen (currently without touch) and try and keep the best keyboard experience.

The Keyboard i am currently using (model M of course) has 14 keys across most of its 5 rows, so a 14x5 matrix would only use 19 of my 22 free gpio pins (result)

the next problem is to see if 14 buttons will fit across the space beneath the screen. I fired up the eagles, and lo and behold, i could just about squeeze them in, JUST!!

clearly nothing is actually connected yet, there isnt even any board bounds on there, just a pi, tft, and 14 buttons. Looks like this could work....
