Why is this a connector?

This is due to the possibility to use those as gpio pins. It is a kind of weird design (see schematic). According to @xobs, they can be used as resistive touch sensors (with internal pulldown and a 3v3 plane on top of the board) but it seems to be fairly untested.

I don't see them connected anywhere on schematic?

Yes, they are just exposed pads on the PCB

OK. It sounds like they should really be 4 connectors, Connector("pin", 0, "XX") and so on.

Also, is the "Fomu Hacker" different from normal "Fomu"? /cc @mithro |

See the the fomu tutorial section hardware. |
