Basix & Connex Interface Design

As of the Summer 2009, Gumstix no longer sells the PXA255-based Gumstix basix or connex product lines, as per this notice.

==========================

Gumstix basix and connex motherboards provide a connector system for the attachment of the wide range of gumstix expansion boards or custom-built expansion boards in a 2-board or 3-board motherboard/daughterboard configuration.

Gumstix maintains a repository of schematics for the interfaces of our expansion boards.

Gumstix basix motherboards have one 60-pin hirose connector while the connex motherboards have both a 60-pin hirose connector and a 92-pin bus header.

Since March, 2006, Gumstix has been shipping:
