Two new expansion modules feature the Stackable Unified Module Interconnect Technology (SUMIT) interface scheme developed by the Small Form Factor Special Interest Group (SFF-SIG). These two expansion cards from VersaLogic, dual Gigabit Ethernet expansion, and an in-stack DC/DC power supply, add additional flexibility to the company’s SUMIT-based line of products.

The PC/104-sized expansion modules are suitable for systems that need a small (3.55” x 3.78”) footprint. The SUMIT interface makes it easier for design engineers to add both standard and custom expansion boards to the system, since it offers both low- and high-speed signals. This includes PCI Express (PCIe) lanes, USB ports, LPC, SPI and SMB. To support legacy applications, these new accessory cards are also equipped with a PC/104 ISA feed-through connector.

The VL-EPMs-E1 Ethernet card features both high-speed Ethernet channels and optional wireless functionality via a PCI Express Mini Card interface. The VL-EPMs-PS1 power supply accepts +9V to +40 Vdc input and provide +5V and ±12 V output (up to 50 watts) for powering the embedded board stack. Customization is available including conformal coating, BIOS customizations, revision locks, custom labeling, high-G shock and vibration treatment, custom testing and screening, etc. VersaLogic’s accessory modules can be used to complement any SUMIT-enabled SBC to form a complete SUMIT ecosystem, and can be mixed with legacy PC/104 modules. They are compatible with any SUMIT-based SBC, including VersaLogic’s Z5xx Atom PC/104-sized board, and the Core2 Duo EPIC-sized SBC. Pricing in OEM quantities for the VL-EPMs-E1 is around $250, and around $200 for the VL-EPMs-PS1.
