Board Extension for DE1-SoC

Hello, I'm looking for a solution how to connect to make "available" the DE1-SoC board for sensor boards with limited number of contacts, e.g. from here: http://store.digilentinc.com/pmod-exp...

You mean "nest" at other side of 40-pin ribbon cable several "low-pins" breakout headers connected to several let say sensor modules ?

In this case power problem arises: each of these two 40-pin headers disposes only 2 PWR and 2 GND (please see the snapshot of schematic fragment).

So only 2 sensor modules per header can be connected this way.

I envisaged anther solution, like that realized for Zync MicroZed board: FPGA board is inserted into I/O Carrier Card that provides access to 12 Pmod-based external modules (please, see the snapshot below).
