 EPIC
format CPU with integrated autocalibrating analog I/O, digital I/O and
DC/DC power supply
Neptune introduces a new concept in small form factor
embedded SBCs. The CPU core consists of an ETX module which mounts on
the bottom side of the board for improved thermal management. This technique
provides more room on the main board for I/O features. The result is
an efficient, cost-effective, reliable, and compact embedded SBC rich
in I/O and user benefits. Neptune is the first 6-in-1 embedded SBC, integrating
processor, system I/O, data acquisition, and even a DC/DC power supply
onto a single board in the compact EPIC format.
You can select from a wide range of ETX CPU modules from
a world-class supplier to tailor Neptune’s price and performance
to your application and budget. A PC/104-Plus expansion socket enables
you to add still more I/O or features if needed, and the built-in 5-28V
input DC/DC power supply provides flexibility in integrating the board
with your system power supply. These features give Neptune an unsurpassed
level of value and flexibility in a small form factor embedded SBC.
Benefits of 6-in-1 Integration
 Less
Space: Smaller and thinner than a stack of PC/104 boards
Lower Cost: An integrated solution eliminates extra
PCBs and connectors to lower the unit cost
Higher Reliability: Less interconnects and components,
resulting in higher reliability
More Rugged: The flatter profile and reduction in connectors
makes Neptune far more rugged in mobile applications
Single Vendor: Purchasing and stocking are easier with
a single board
Saves Time: Assembly effort is dramatically reduced,
shortening your total system integration time
Data Acquisition
• 32 analog inputs, 16-bit A/D, 250KHz sample rate
• 4 analog outputs, 12-bit D/A
• 24 digital I/O, 3.3V/5V compatible
• 8 opto-isolated digital inputs, 3-24V range
• 8 opto-isolated digital outputs, 3-24V range
• 2 counter/timers for A/D sample rate control, event counting/timing,
and programmable interrupts
• Universal Driver software support for C programming under Windows and
Linux
Benefits of an ETX Processor Core
• Choice of price/performance: Neptune is available with a low-power
AMD LX800 up to an Intel Core 2 Duo, 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’s top-performing autocalibration circuitry
enables you to calibrate the analog circuits under software control at
any time, maintaining best accuracy under all conditions. Temperature-
and time-dependent measurement drift is eliminated, as the board can
be calibrated as often as desired in just a few seconds to ensure accurate
readings in all environments.
Thermal Management
Neptune places the processor on the bottom side of the
board. An integrated heat spreader makes thermal contact with the heat
generating components on the 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.
