I felt the easiest thing would be to have an on board Nano socket to directly plug a Nano into. If you want Ethernet, than that could plug in with the Nano. Would you need an Uno as the Nano can do what the Uno can? So that just leaves the Mega. So I thought a row of breakout screw terminals could be present to allow wired connection to a Mega, or indeed an Uno if you really?wanted."
Let me say first up I have never used any Arduino/Pi etc so don't know how the onboard jumpers are positioned or wired but am interested and have been following this thread.
The best way to do a one fits all board is to use jumpers.
Design the board as an input section, your sockets etc. and a working section to plug in the Arduino XXX The traces from the input that need adjustment should all end in a solder pad and so too the inputs to the controller, these pads should be placed near to each other.
Short wire links can be placed by the user to suit whichever controller is to be used.

Hi Tony,
Good to hear from you. BTW, it was actually me that wrote that and not Blair. Anyway thanks for your very useful input there. Having a think about a possible configuration, I also came to the conclusion that some jumpers were going to be needed. I was thinking of the little jumper plugs that plug into headers rather than solder pads. My reason was so that anyone wanting to reconfigure a board just had to move a few jumpers rather than get the soldering iron out! What would your preference be?
