Re: [Gumstix-users] Robostix, GPSstix

[Rodrigo S. <rod...@gm...>]

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.
cheers

Rodrigo
