Adam,Are you still working a the Giant Board? This would be a good companion board: https://www.tindie.com/products/arturo182/keyboard-featherwing-qwerty-keyboard-26-lcd/
There is a "Solder Party" channel forum on discord.com. Groguard discusses using the Giant Boards with the keyboard FeatherWing there.
That could be a lot of fun. I am considering one myself, but I have no feather boards to drive it.
