Overo, the next generation of gumstix motherboards, has been designed to reduce the task in designing custom daughtercards to, more or less, adding a minimum of passive components, connectors, and any required dedicated video management IC such as the TFP410 or any required logic level interface.

 

 

 

 

 

 

 

 

 

 

 

 

 

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:

Note: schematic images and charts below are from the point of view of the gumstix looking at the connector from the daughtercard's point of view, these signals are mirrored

 

Overo & JTAG

Gumstix does not support JTAG on Overo motherboards. For debugging purposes, Gumstix recommends the use of a bootable microSD card. Instructions for creating a bootable microSD card are posted here .
