VersaLogic Corp. has launched their M1 line of expansion modules, providing industry-standard I/O interfaces for SUMIT-based embedded systems. With extended temperature operation and extensive ruggedization, VersaLogic's M1 multi-I/O cards are targeted for SUMIT-based applications requiring USB, SATA, PCI Express, and mSATA capabilities. 

Based on the SUMIT interface standard, the M1 boards support SUMIT and PC/104 stackable expansion buses on an industry-standard 90 mm x 96 mm (3.55" x 3.78") expansion module. I/O requirements supported on various M1 models include:

  • Up to four USB ports
  • Dual drive SATA controller with latching connectors compatible with both solid-state drives (SSDs) and rotating drives
  • PCI Express Mini Card socket for plug-in Wi-Fi modems, GPS receivers, flash data storage, and other functions
  • mSATA interface that provides high-throughput, low-latency flash storage capabilities utilizing small form factor mSATA SSDs

The M1 boards are designed for full industrial temperature operation (-40° to +85°C). They are built to withstand thermal extremes and meet MIL-STD-202G specifications for mechanical shock (20g) 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.

Standard drivers are available for compatibility with most x86 operating systems including Windows, Windows Embedded, Linux, VxWorks, and QNX.


The M1 SUMIT expansion modules are RoHS compliant, manufactured to IPC-A-610 Class 2 standards, and include VersaLogic's 5+ year production life guarantee. The M1 boards are customizable in low OEM quantities. Customization options include conformal coating, revision locks, custom labeling, and customized testing and screening.

VersaLogic's SUMIT expansion modules can be used to complement any SUMIT-based SBC including VersaLogic's PC/104-sized Intel Atom Z5xx (Menlow XL) or EPIC-sized Intel Core2 Duo single board computers.

The VL-EPMs-M1 expansion modules are available from stock now. Pricing starts at $128.00 in OEM quantities. Contact Sales@VersaLogic.com or visit www.VersaLogic.com for more information. A datasheet is available here.
