LinZhiqiang, I have created your question in the Galileo Forums.
hi, have anyone has Galileo Orcad DSN File?
If you are looking for the Galileo Boards (Gen1 and Gen2) schematic you can check them here:
Intel® Galileo Schematic
Intel® Galileo Gen 2 Schematic
However, the only format available for the schematics is pdf.
Retrieving data ...
