Pentium-based ETX module supports Linux

Jan 26, 2005 — by LinuxDevices Staff — from the LinuxDevices Archive

Adlink has released an ETX form-factor single-board computer (SBC) that supports embedded Linux on Celeron and Pentium processors. Target markets for the ETX-IM333 include medical automation, instrumentation, gaming, POS, mobile computing, and transportation, according to the company.

The ETX-IM333 is based on an Intel 855GME chipset and supports Pentium M processors from 1.1 GHz to 2.0 GHz, as well as Celeron M processors from 600 MHz to 1.3 GHz. According to Adlink, the chipset and processors are part of Intel's embedded-oriented program that guarantees extended production lifespans, although the company did not specify the length of availability.

The module supports CRT video with resolution up to 1600 x 1200, and LVDS display with resolution up to 1280 x 1024. I/O ports include 10/100 Base-T Ethernet, Ultra ATA EIDE, four USB 2.0 ports, AC '97 Audio, serial and parallel ports, and keyboard/mouse. Other features of interest to embedded developers include: RS-232 console redirection; CMOS EEPROM backup for BIOS settings to allow battery-less operation; boot from USB, diskette, or CD-ROM; and PXE remote boot. An optional video encoder translates PC graphics data at up to 1280×1024 resolution into PAL (50Hz) or NTSC (60Hz) video signals, and the encoder can also output Y, PB, and PR signals for HDTV i1080 monitors.

From the operating system perspective, Adlink says that all of its ETX modules are supported by BSPs for embedded Linux, VxWorks, Windows XP Embedded, and Windows CE.

About ETX

The ETX module format was originated by JUMPtec, which was subsequently acquired by Kontron. The modules are generally installed on application specific baseboards much like an integrated circuit component, in a “host” site comprised of four low profile, surface mount connectors. The baseboard provides the drive electronics and physical connectors for the I/O originating on the ETX module. Additional I/O and application-specific subsystems can be integrated on the baseboard, designed as PCI or ISA bus peripherals.

Pricing and Availability

The ETX-IM333 is priced at $975 and is available from stock with OEM volume discounts, according to Adlink.
