Indecision

I am in two minds whether to go as a single board of to split the board into two?

Here is the a schematic with the keyboard separated from the PLA:

The advantages are:

• One project becomes two smaller projects.
• A smaller footprint (the boards can be stacked).
• I can finish the keyboard layout and get the PCB board made.
• I can drop the PLA if I go for a microprocessor project.

I think getting the board made (as it takes four weeks) sounds like a good idea.

Stacking the boards (the PLA underneath) seem pretty straight forward.
