With the end-of-life of the 855 chipset in all form factors, popular Pentium® M and Celeron® M SBCs need to be replaced with power-efficient Atom-class products, said Colin McCracken, vice president of marketing at Diamond Systems. Featuring conduction cooling, Diamond's new Aurora SBC stretches program budgets by providing an unmatched feature set. Half the size, weight, power AND cost is a compelling migration value proposition. For basic command, control, data collection, portable, vehicle upgrade and communications applications, the days of $1,000+ mid-range rugged SBCs are numbered thanks to Aurora’s perfect-fit solution.
Aurora combines the 1.6GHz Atom Z530 processor with SODIMM RAM up to 2GB, Gigabit Ethernet, USB Flashdisk, Serial ATA (SATA), four RS-232 serial ports (two with RS-422/485 capability), four USB 2.0 ports, PS/2 keyboard and mouse, and both SUMIT-A and PC/104 ISA bus expansion. Prior to Aurora, this extensive feature set was typically accomplished by two-board stacks or SBCs with wings (form factor excursions). Compared to COM Express® modules which require +12V input and full custom carrier card designs, Aurora saves power by operating off a single low voltage +5V input, yet still allows I/O customization in the form of a plug-in SUMIT module. Diamond supports Windows® Embedded Standard and Linux® 2.6 operating systems.
Rugged features include -40oC to +71oC operation and an innovative new SO-DIMM solution with optional mounting holes for ruggedness. Diamond's rugged RAM offering will be manufactured by multiple embedded suppliers. The on-board SATA connector interfaces to SSDs with short 3 latching cables and no need for external SATA convertor. Diamond chose to convert IDE (PATA) to SATA on-board since IDE drives are EOL and SSDs are at risk of higher prices and shorter lifecycle compared to 2.5 SATA SSDs. Conduction cooling is the ideal solution for sealed (waterproof / dustproof) metal enclosures in order to prevent thermal runaway and maximize the reliability and longevity of electronics.
Aurora is well suited as a basic x86 controller for a range of applications. SUMIT-A is a space-efficient interface for PCI Express x1, USB, LPC and I2C buses. The combination of SUMIT and PC/104 expansion interfaces is on a growth trajectory to support the largest overall ecosystem of stackable I/O cards, as PCI chips are becoming EOL in favor of PCI Express chips. System OEMs who use PC/104 I/O cards can now continue to use such cards without having to increase their stack height with a bridge card, or completely re-engineer their software and stack for PCI-based I/O cards.
Supported operating systems currently include Windows XP and Linux 2.6, with support for additional OSes and RTOSes (real-time OSes) available on request.
