Fanless embedded PC likes to play rough

Jun 9, 2010 — by Eric Brown — from the LinuxDevices Archive — 4 views

Avalue is readying a rugged, fanless, embedded computer for vehicles, industrial machines, and military equipment, equipped with a dual-core Intel Atom D510 processor. The ERS-PNV series offers dual gigabit Ethernet ports, five USB 2.0 ports, three serial ports, plus both CompactFlash and SATA storage, says the company.

The ERS-PNV comes standard with the dual-core Intel Atom D510, but can also be deployed with one of the other two single-core D410 or N450 "Pineview" Atoms, says Avalue. Supporting up to 2GB of DDR2 667MHz SDRAM, the computer provides both a CompactFlash (CF) slot and dual SATA ports, with a mounting kit for a 2.5-inch hard disk drive (HDD), says the company.

The ERS-PNV is further equipped with dual gigabit Ethernet ports and five USB 2.0 ports, one of them front-facing, says Avalue. One of the USB ports can hold an optional 802.11b/g wireless module, says the company, and a Mini PCIe slot offers the opportunity for further wireless expansion.

Three serial ports are said to be provided, with an option for three more front-facing serial ports available via an LPC to COM module. A VGA port and audio I/O round out the set of available interfaces.

Passive aluminum heat dissipation fins sit atop the 10.67 x 4.90 x 2.17-inch chassis, enabling fanless cooling, says Avalue. The horizontal deployment of the 3.5-inch single board computer (SBC) and HDD within the system also helps to improve cooling efficiency, providing support for temperatures ranging from 32 to 122 deg. F (0 to 50 deg. C), says the company.

Anti-vibration has been tested at up to 5 Grms, and anti-shock up to 50 Grms, claims Avalue. Other ruggedization features are said to include a secure metal covering for the CF slot, and an optional lockable or industry-grade Phoenix-type power connector plug that supports a stable +9V to +32V wide voltage input.

A service window on the bottom cover of the system provides access to the internal system board and hard drive, says the company.

Specifications listed for the ERS-PNV include:

  • Processor — Intel Atom D510 with dual 1.66GHz CPUs (optional single-core D410 or N450 1.66GHz); Intel ICH8-M chipset

The ERS-PNV is available this month at an unspecified price. Operating system support was not detailed. More information on the ERS-PNV may be found here.

Other similar Avalue ERS systems include the Atom N270-based ERS-AT270, and the Intel Core 2 Duo-based ERS-945, says Avalue.
