Connection ports extension

#1

Is there a possibility to extend the connections of a Makeblock kit.
My Uno just has 4 ports, my Auriga five (port 6-10).

For a Project on school I need to use more modules. I hope there will be a hub with more connection possibilities.
But How do I solve it jet ?

What do you plan to connect?

#3

The servo pack (over the RJ45 module)
The led strip over RJ45 module.
2x The RGB led module
The dotmatrix
The 7-segment display
The 4 button/switch module
And maybe the lightsensor module.

That makes 8 ports and my Auriga has 5, Mbot has 4 …

Probably the cheapest solution is an additional main controller.
