Re: [Gumstix-users] What parts needed with basix 400 bt ?

Ummm. The usb cable isn't a programming cable. Its just a usb cable
that allows the gumstix to act like a usb device when connected to a
PC. Probably not useful for robotics unless you're also going to be
using a PC as a host of some type.

The USB cable plugs into some of the daughtercards, like the
breakout-gs, or the waysmall-stuart. These daughtercards have a 60-pin
hirose connector on them which is where the gumstix plugs in. This
page:
http://docwiki.gumstix.org/Packs_and_boards_setup
shows how an audiostix, gumstix, and netCF card ll plug together,

The breakout-gs and audiostix-2 boards both provide fairly easy access
to the SPI signals.

> Need also I a Hirose connector ?

The gumstix has a 60-pin hirose connector and a 92-pin hirose
connector. If you goto this page:
http://gumstix.com/spexExpnsion.html
and click compare, there is a column that says motherboard
compatability which says "connex only". Theses are boards which plug
into the 92-pin hirose connector. The boards which say "any gumstix"
are boards which plug into the 60-pin hirose connector.

So to make a stack, you can have one board that plugs into the 60-pin
connector, the gumstix itself, and one board that plugs into the
92-pin connector (except for the basix which doesn't have a 92-pin
connector).
