Topic: A backplane or motherboard for Shields and CPUs (Read 136 times) previous topic - next topic


It is difficult to stack several shields now. A working machine easily needs more than one shield, like one or more IO shields, display shield and perhaps a wireless shield or something else. You cannot stack them. Well, the display must be the uppermost but there are problems with other shields too.

So put them side by side on a backplane. Because there are pins that are more widely used, like serial in/out, than others you need a method to switch, multiplex or control where your data goes. Not too hard if you are a HW designer.

A project with a backplane is not a beginner project, but a beginner would not need several shields either.


Hmmm, very simple board. You could design that yourself using a free PCB design tool (there are many, but Eagle won't work because the board would be larger than allowed by the free version). Nothing but holes for pins/sockets and some copper traces. Then have it made in China (e.g. Seeedstudio) where small quantities are very inexpensive.

I could but I think others would have some use for that kind of board, so it should be an Arduino board. But then, those who need it are able to make it themselves.


If someone were to design the board, it could be posted as a publicly orderable item on Seeedstudio. The only other thing you'd need would be some pin headers and sockets, probably also available from them (I'm guessing).
