Hole Reference Description Size

mounting holes Spacing
determined by SMARC
specification for 82mm x
50mm Modules.
Typically these holes have
3mm length press fit or
swaged clearance standoffs on
the Module side.
These holes are typically
countersunk on the far side of
the plate, to allow the heat
spreader plate to be flush with
a secondary heat sink.
Hole size depends on standoffs used.
Standoff diameter must be compatible
with SMARC Module mounting hole pad
and hole size (6.0mm pads, 2.7mm holes
on the Module). The holes and standoffs
are for use with M2.5 screw hardware.
The far side of these holes are
counter‐sunk to allow the attachment
screw to be flush with the far side heat
spreader surface.
B Not Defined
C Fixed location holes to allow
the attachment of a heat sink
to the heat spreader, or to
allow the heat spreader to be
secured to a chassis wall that
can serve as a heat sink. M3 threaded holes
