Re: [Gumstix-users] Audiostix, UCB1400 and PXA GPIOs

[Bhaskar M. <bha...@gm...>]

Hi Darren,
        the X1 connector on the audiostix will have the ucb gpio pins
in it. The schematic has a 12pin X1 connector that contains all the
GPIO pins and the agnd, avdd signals.
also from the wiki 
"The X1 X2 X3 X4 connectors are from the MOLEX 53398 series. "
        my audiostix is not here yet but i think that the pads should be there.
bhaskar.
