1.2 SUMIT Socket Resources
Aurora’s SUMIT-A expansion socket provides the host interface resource support indicated in the table below. For
further details on the SUMIT expansion standard, visit
SFF-SIG.org/sumit.html
.
1.3 Software Compatibility
Aurora is compatible with Linux, Windows XP, and Windows Embedded Standard. All necessary drivers for these
operating systems are provided with the product.
1.4 Thermal Considerations and Heatspreader
All models of Aurora are specified for a -40
o
C to +80
o
C operating range, the temperature being measured at the
outside surface of the heatspreader. Diamond provides a heatspreader attached to the Aurora single board
computer as a conductive cooled thermal layer. However, this heatspreader by itself does not constitute the
complete thermal solution necessary for any specific implementation, but provides a common interface between
the single board computer and the customer’s implementation-specific thermal solution.
The outside surface of the Aurora heatspreader must be kept at a temperature not to 80
o
C. If your
environment causes the temperature on the outside surface of the heatspreader to exceed this temperature, you
are responsible for removing the additional heat from the system through either an additional passive thermal
solution or fan solution.
Aurora’s integrated heatspreader makes thermal contact with the heat generating components and provides a flat
surface on the bottom of the assembly for mating to the system enclosure. This technique facilitates efficient
removal of heat from the SBC without the need for a fan. Four mounting holes on the bottom of the conduction
cooled heatspreader are provided to mount Aurora in an enclosure or to a bulkhead. These mounting holes are
#6-32 threaded holes on 2.8" centers.
