Raspberry PI is ideal for it's designed application. It's also at a price sweetspot for alot of other applications. However some of these applications would benefit from only exposing power and ethernet connections to the end user, along with peripheral connections.
This presents a problem with power and ethernet being at different ends of the RPi board.
It should be possible to remove the ethernet, and USB connectors and replace with headers to allow connection to a motherboard / daughterboard along with the GPIO header.
To do this accurate dimensions are required, and a 'final' GPIO connector configuration available. Once this information is available it should be possible to produce a (shield / cape) type outline in the popular PCB packages.
Does anyone have an interest in this ?
Perhaps if there is enough interest then RaspberryPi boards could be shipped without USB / ethernet connectors installed.
Possible applications / benifits
Use off the shelf casing solutions
Easier POE solutions presenting only a single RJ45 socket
Embedded USB peripherals
