SUMIT-enabled Embedded ModuleRoHS-compliant



The VL-EPHs-S1 expansion module provides SATA interface capabilities for any SUMIT-based embedded system. With a small footprint, simplified interface, and extensive ruggedization, the VL-EPHs-S1 is an ideal solution for all SUMITsystems that require SATA capabilities.

The VL-EPHs-S1 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-EPHs-S1 provides a rugged embedded computer solution with an excellent cost of ownership. The VL-EPHs-S1 is manufactured and tested to the highest quality standards and is fully RoHS compliant. Customization is available, even in low OEM quantities.


The VL-EPHs-S1 expansion module is a 90 mm x 32 mm (3.54 x 1.26) mezzanine SUMIT-micro card that provides SATA signals via the PCIe lane of the SUMIT-A connector. It mounts to the top of the SUMIT stack using two hardware standoffs. The on-board SATA controller supports two SATA drives in normal, RAID 0 (Fast), or RAID 1 (Safe) configuration. The two standard latching SATA connectors are compatible with traditional rotating drives, as well as solid-state SATA drives. An EEPROM BIOS extension enables booting from a SATA device.

Designed for full industrial (-40 to +85C) temperature operation; the VL-EPHs-S1 meets MIL-STD-202G specifications for mechanical shock and vibration for use in harsh environments.

The VL-EPHs-S1 is compatible with a variety of popular operating systems including Windows, Windows Embedded, Linux, VxWorks, and QNX.
