Attached SGI_O2_SYSTEM_PROM_SOCKET_ADAPTER_A00_RELEASE.zip archive.<\/p>\n\n\n\n

It contains the following:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

1.SCH_BRD – contains editable schematic and board file. Format is Eagle CAD, but they can be imported in other tools, like Kicad.<\/p>\n\n\n\n

2.SCH_PDF- schematic in pdf format.<\/p>\n\n\n\n

3.P&P – pick and place files<\/p>\n\n\n\n

4.BOM<\/p>\n\n\n\n

5.GERBER – gerber files<\/p>\n\n\n\n

Notes:
-the two FFCs are not identical, pay attention at the photos to see how they need to be installed (both FFCs and the adapter PCBs are marked with L and R)
-header pins that plug into the Dallas socket need to be the machined type, round
-not possible to install R10k\/R12k CPU module when the socket adapter is installed (not really an issue as anyone using this will likely use it for RM7**** development).<\/p>\n\n\n\n
