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.

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.

SYSTEM I/O FEATURES
All Neptune models include the following standard CPU I/O features in addition to the data acquisition and DC/DC power supply.
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.
