BENEFITS
OF
AN
ETX
PROCSSOR
CORE
Choice
of
Price/Performance
Neptune
is
available
with
a
low
power
AMD
LX800
up
to
an
Intel
Atom
N270
so
you
can
obtain
exactly
the
performance
and
price
point
you
need.
Protection
from
Obsolescence
Easily
switch
processor
modules
in
case
of
processor
end
of
life.
Easy
Upgrade
ETX
CPUs
are
interchangeable,
allowing
you
to
easily
upgrade
your
system
with
minimal
or
no
redesign.
Low
Cost
ETX
modules
cost
less
than
their
equivalent
single
board
computer,
resulting
in
a
lower
total
cost
for
Neptune.

AUTOCALIBRATION
FOR
BEST
MEASUREMENT
ACCURACY
Diamond
Systems’
top
‐
performing
autocalibration
circuitry
enables
you
to
calibrate
the
analog
circuits
under
software
control
at
any
time,
maintaining
best
accuracy
under
any
conditions.
Temperature
and
time
dependent
measurement
drift
is
eliminated,
as
the
SBC
can
be
calibrated
as
often
as
desired
in
just
a
few
seconds
to
ensure
accurate
readings
in
all
environmental
conditions.
THERMAL
MANAGEMENT
Neptune
places
the
processor
on
the
bottom
side
of
the
baseboard.
An
integrated
heat
spreader
makes
thermal
contact
with
the
heat
generating
components
on
the
ETX
CPU
module
and
provides
a
flat
surface
on
the
bottom
side
for
mating
to
the
system
enclosure.
This
technique
provides
for
efficient
removal
of
heat
from
the
CPU
without
the
need
for
a
fan.
