Hi Toby,

I use the following scheme:
gumstix <----(hirose)---->gpsstix<--------(i2c)--------->robostix
i mean, i use the breakout of the gpsstix of the signals from the gumstix, and connected SDA, SCL and GND properly... (not connected the VCC because the different voltages involved)
soldered 3 cables on the gpsstix back.

Not at the same time. You can however, plug the gpsstix into the
gumstix and connect up the robostix via the i2c bus.

You'll need to worry about voltage conversion. There is a 3.3v to 5v
voltage conversion chip for i2c already on the robostix which you can
make use of (requires soldering some wires to the chip) or you can
something external.
