Is it possible to add a Raspberry Pi later after building Nybble with only the Nyboard? Or should I go ahead and install it during the build

@Tom Swann I must admit, getting the connections to the Nyboard with the Pi configuration was quite difficult, thats because the Nyboard is positioned to the top end of Nybbles frame in order to make room for the Pi USB and Ethernet ports, as a result servo cables 11 and 10 have to be streched to their limit, as shown below.
Servo cable 11 is fully streched to pin 9
Rongzhong has kindly pointed out that it is possible to reassign the pins as they are declared as constants in the code.
So I will be switching pins 9 and 11 over as well as, 14 and 12 which will provide a little slack on both cables.
Also, since the Nyboard is mounted above the frame in the Pi configuration and not underneath as with Nyboard only config. The servo cable connectors will not sit flush, you'll need to tease them in gently at an angle as below.
But just thinking about it, since the Pi0 doesn't require the space allowance of a full size Pi, perhaps the Nyboard only config will support mounting a Pi0?? Food for after-thought.
