Diamond Systems Corp. reports that its new single board computer (SBC), Neptune, features the industry's highest integration and is the most scalable EPIC form factor SBC. Neptune uses a standard ETX module interface to support the CPU modules, with a choice of the following modules installed on the Neptune carrier board: 500MHz AMD Geode LX 800, 1.0GHz Celeron M 373 and 1.4GHz Intel Pentium M 738. Incorporating the equivalent of five PC/104 I/O modules on a single board, Neptune features a 115mm x 165mm EPIC footprint. Available I/O includes USB 2.0 ports, Serial ATA (S-ATA) and EIDE hard drive interfaces including CompactFlash socket and IDE Flashdisk interface, 10/100 and GbE controllers, RS-232 serial ports (some with RS422/485 capability), AC'97 audio, and legacy keyboard and mouse interfaces, and a PC/104-Plus expansion (PCI and ISA buses) interface.

Graphics engines drive independent CRT and LVDS flat-panel displays according to the chipset of the installed ETX module. Neptune offers a range of memory sizes from 512MB of 333MHz DDR RAM to 2GB of 667MHz DDR2 SO-DIMM RAM installed onto the ETX module.

Available with integrated DAQ capability, the SBC offers 32 single-ended (16 differential) analogue inputs with 16bit autocalibration A/D, 250kHz sample rate and 1024 sample buffer, four analogue outputs with 12bit D/A and 100kHz waveform output capability, 24 programmable digital I/O lines, 8 optically isolated digital inputs, 8 optically isolated digital outputs and two counter/timers. The analogue I/O circuitry supports both interrupt and DMA A/D transfers.

Diamond's Universal Driver programming software for Linux, Windows XP and CE and QNX is included. Neptune accepts a wide input voltage range of 5-28Vdc, making it well suited for many industrial and vehicular embedded applications. Standard operating temperature is 0-60°C, with optional extended operating temperature range that depends on the installed ETX module. Optional conformal coating is also available.

Development kits are available. The Neptune SBC is available in 500MHz, 1GHz and 1.4GHz versions, with and without DAQ. Neptune and its related products are all available early Q2 2008 with prices starting under Rs.36,291.47 ($900). Volume discounts are available.
