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.
