Hallo,
in my 172 cockpit I have to use 2 Megas and 1 Uno.
I made a "distribuition board" to share the GND: both Megas and the Uno are connected to the board so all the system is sharing GND.
Now i'm wiring the +5v, so my super-newbie question is:
can I share also the +5v coming from different Arduinos?? Or I have to build 3 x 5v distribuition boards, one for mega1, one for Mega2 and one for Uno??.
Thanks ...

theoretically it won't be an issue, but if your supply is from different units it might. I would keep them separated.

another issue is the power requirements of each arduino and the connected peripherals. You might want to consider a separate supply for the boards and peripherals and then only have data and GND to the USB port.
