Play along - create a PinePhone keyboard

[x0r]

I'd like to remind everyone that the BlackBerries had a teeny tiny trackball(or an optical trackpad later on).
You could still get them as modules for Arduinos, so it seems to be an option if anybody wants to incorporate them into their keyboard designs.

What is the width of the phone? There are 10 horizontal keys. How much would it fit vertically?

I think that big keys like spaces or esc, back, pgup, down, enter would fit easily.


To operate a browser, pgup, down, esc and tab are more important than even a space.

Maybe you will write a survey, though?
e.g. [0-9] [A-Zaz] [language char] ;'\,.<>/?
