Kontron ETX-LX2

Low powered but high performance

Manufacturer: Kontron
Kontron ETX-LX2

The ETX-LX2 (Embedded Technology eXtended) is a highly integrated and fast PC module with extremely low power consumption.  It allows, due to the used AMD LX800 processor, the usage of the board without active cooling in applications, where space limitations (the maximum height without heat sink is only 10 mm!) are major requirements. Despite the very little board dimensions, the EXT-LX2 offers all standard interfaces such as sound, Ethernet, USB2.0, graphic and TVout. The AC97 compatible sound chip is supported by most operating systems. For networking purposes, the ETX-LX2 comes with a Davicom 10/100 MBit Ethernet controller.

You´re looking for a secure and EMI tolerant boot medium and want to be unlimited in your media capacity choice? A CompactFlash™ socket is already mounted on the ETX-LX2 and offers you a lot of possibilities. For further expansions two IDE ports with Ultra66 DMA capabilities are available. They do not provide the PCI bus only, the ISA bus signals are also available. A lot of existing ISA boards can still be used via an ISA slot on a baseboard. This avoids expensive redesigns and well proven ISA cards to PCI versions for standard PC motherboards. Despite the unbelievable variety of functionality, the EXT-LX2 is a very inexpensive choice, the cost-effectiveness of this device is unbeatable. It also takes advantage of the new ETX 3.0 specification that allows for 2 Serial ATA ports without violating the existing ETX 2.8 pin usage (see picture on right)


The ETX-LX went EOL due to the fact that Intel no longer manufacturer the Ethernet controller used on that board (Intel ® 82551ER). The ETX-LX2 uses an alternative 10/100 controller, the Davicom DM9102H. Additionally, Kontron changed one other component due to obsolescence reasons (AC97 codec ALC203-LF replaced by LM4549B AC97 codec) and moved one other IC to optimise memory socket usage.

Kontron are 100% sure that aside from requiring a different Ethernet driver that the ETX-LX2 is a 100% backwards replacement for the ETX-LX. To summarise:

  • Compliant to existing Baseboards
  • Same mechanical layout and dimensions
  • No change in power and performance
  • Uses same memory modules as ETX-LX
  • Uses same heatspreaders as ETX-LX
