The VL-EPMs-E1 is a SUMIT-based dual gigabit Ethernet (GbE) expansion module with a PCI Express Mini Card socket. This versatile expansion module is the ideal solution for high-bandwidth and/or wireless network applications in a wide range of applications including defense, aerospace, homeland security, and industrial automation where a small footprint and extended temperature operation are crucial design factors.

Based on the industry standard PC/104 footprint, the VL-EPMs-E1 features the SUMIT expansion interface. SUMIT provides a stackable expansion interface that supports both high- and low-speed signals. This simplifies adding both standard and custom I/O boards to the system. The VL-EPMs-E1 expansion interfaces include PCIe, USB, LPC, SPI, SMBus, as well as optional ISA bus support for PC/104 modules.

Like all VersaLogic products, the VL-EPMs-E1 is designed to support OEM applications where high reliability and long-term availability are required. From application design-in to 5+ guaranteed years of production life, the VL-EPMs-E1 provides a durable embedded computer solution with an exceptional cost of ownership. The E1 is manufactured and tested to the highest quality standards and is fully RoHS compliant. Customization is available, even in low OEM quantities.


The VL-EPMs-E1 is a SUMIT-104 expansion module that provides two gigabit Ethernet channels based on Intel® 82574L controllers. Additional system expansion and communications flexibility is available via the on-board PCI Express Mini Cards socket. The socket is compatible with:

  • 802.11a/b/g Wi-Fi network adapters
  • GPS radio modules (for global location and precision time stamping)
  • 3G modems
  • Solid-state flash drives (SSDs)

This GbE module offers low power consumption (3.5 watts) and low thermal dissipation for heat sensitive applications, as well as transient voltage suppression (TVS) on the Ethernet connections to protect from power spikes and surges. With an Ethernet buffer of 16 KB RAM, data is easily stored and retrieved. Extended temperature operation provides reliability in harsh environments.

The VL-EPMs-E1 works with the entire family of industry-standard SUMIT-based computer and add-on boards.

The VL-EPMs-E1 is compatible with a variety of popular operating systems, including Windows, Windows Embedded, Linux, VxWorks, and QNX.
