Fanless ETX module targets industrial applications

Sep 26, 2008 — by Eric Brown — from the LinuxDevices Archive — 3 views

Avalue is shipping a module using Kontron's ETX “computer-on-module” form-factor, targeting industrial applications. The Linux-compatible ESM-910ETX supports dual-channel LVDS for simultaneous display from two sources, has an Intel Celeron M processor clocked at 600MHz, and uses dual-channel DDR2 memory, the… company says.

Touted as an upgrade replacement for previous modules that were based on Intel's 852GM chipset, the ESM-910ETX offers higher component integration, greater bandwidth, and better power efficiency than these older designs, claims Taiwan-based Avalue. Applications are said to include industrial automation, medical, transportation, measurement, point-of-sale (POS), kiosk, thin client, and digital control devices.

The fanless ESM-910ETX uses Intel's 910GMLE chipset, which supports dual-channel DDR2 400MHz system memory. The use of DDR2 RAM improves peak memory bandwidth by over 20 percent, and reduces memory power consumption by 50 percent, claims Avalue.

The 4.5 x 3.7-inch ESM-910ETX adheres to Kontron's familiar ETX format, and apparently complies with the ETX 3.0 revision, since it incorporates dual SATA ports. The device also includes a 600MHz Intel Celeron processor, four USB 2.0 ports, and dual serial ports.

Features listed for the ESM-910ETX by Avalue include the following:

  • Processor — Intel Celeron M 600MHz or Intel uFC-BGA 479 Celeron M 600MHz; 512K L2 cache
