Embedded PC/104+ ModuleRoHS-compliant



The VL-EPMs-M1 expansion modules provide access to a variety of I/O ports in SUMIT-based embedded systems. With a full industrial temperature rating and extensive ruggedization, the VL-EPMs-M1 is an ideal solution for SUMIT-based applications that require USB, SATA, PCI Express, and mSATA capabilities. See the Ordering Information section for available models and the port combinations that they provide.

The VL-EPMs-M1 is designed to support OEM applications where high reliability and long-term availability are required. From application design-in support, to the 5+ year production life guarantee, the VL-EPMs-M1 provides a rugged embedded computer solution with an excellent cost of ownership. The VL-EPMs-M1 is manufactured and tested to the highest quality standards and is fully RoHS compliant. Customization is available, even in low OEM quantities.


Based on the SUMIT standard, the VL-EPMs-M1 supports SUMIT and PC/104™ stackable expansion buses on an industry-standard 90 mm x 96 mm (3.55” x 3.78”) expansion module.

  • The VL-EPMs-M1 provides up to four USB ports: two via standard Type A connectors and two via a 10-pin connector.
  • The on-board SATA controller supports two SATA drives. Utilizing a standard latching right angle SATA connector, the VL-EPMs-M1 is compatible with traditional rotating drives, as well as solid-state drives (SSDs). The on-board BIOS extension supports system booting from a SATA device.
  • An optional mSATA interface provides high-throughput, low-latency flash storage capabilities utilizing small form factor mSATA SSDs.
  • An optional PCI Express Mini Card socket accommodates plug-in Wi-Fi modems, GPS receivers, flash data storage, and other cards.

Designed for full industrial (-40° to +85°C) temperature operation, the VL-EPMs-M1 is built to withstand thermal extremes. The VL-EPMs-M1 boards also meet MIL-STD-202G specifications for mechanical shock and vibration for use in harsh environments.

Transient voltage suppression (TVS) devices on all USB channels provide enhanced electrostatic discharge (ESD) protection for the system.

The VL-EPMs-M1 is compatible with a variety of popular operating systems including Windows, Windows Embedded, Linux, VxWorks, and QNX using standard software drivers.
