Atom-based SBC boasts four gigabit ports

Sep 3, 2009 — by Eric Brown — from the LinuxDevices Archive — 7 views

Commell announced a 5.25-inch single board computer (SBC) targeting display-oriented embedded applications. Built around an Intel Atom N270 and Intel 945GSE Express chipset, the LE-575 is equipped with four gigabit Ethernet ports, seven serial ports, and eight USB ports, plus both PCI and Mini PCI slots, the company says.

The LE-575 is aimed at digital signage, kiosk, point-of-sale/service (POS), thin client, digital security, and commercial and industrial control applications, says Taiwan-based Commell. In addition, the board is said to be specifically designed for IDS/IPS, anti-virus, VPN gateway, and UTM (unified threat management) applications, although the company did not mention any specific security features to support that.

Commell refers to the LE-575 as a "5.25-inch miniboard," but the LE-575 actually measures 5.7 x 8.0 inches. The SBC is based on an Intel Atom N270 with up to 2GB DDR2, as well as the usual Intel 945GSE + ICH7M chipset.

The 945GSE chip offers Intel GMA 950 graphics, supporting LVDS or DVI, CRT, HDTV, and multiple simultaneous displays. Specifically, the LE-575 furnishes a standard 18-bit, dual-channel LVDS interface, as well as an optional secondary 18/24-bit LVDS or DVI I/F interface, says the company.

Real-world ports on the edge of the LE-575 include four gigabit Ethernet ports, two USB 2.0 ports, and a COM port. Headers on top of the board provide additional functionality including six additional USB 2.0 ports, six more serial ports, an S/PDIF digital audio output, a floppy connector, and a PS/2 port. Storage interfaces, meanwhile, include dual SATA connections for hard disk storage, an IDE interface supporting a solid-state drive (SSD), and a Compact Flash socket. Expansion is available via dual Mini PCI sockets and a standard PCI slot, Commell adds.

Specifications listed for the LE-575 include:

Commell did not offer pricing or availability information on the LE-575 board. Neither did it mention operating system (OS) support, although the board's standard Intel x86 architecture chips suggest that Linux, Windows, and other major embedded OSes should work fine.
