Rugged, fanless i.MX6 SBC matches COM Express Basic footprint
Feb 2, 2018 — by Rick Lehrbaum — 652 viewsVersalogic has revealed preliminary details of its first Arm-based SBC. The quad-core i.MX6-powered “Tetra” features up to 4GB RAM, 32GB eMMC, and 128K MRAM, plus I/O including GbE, SATA, LVDS, HDMI, USB, serial, CAN, microSD, and miniPCIe, and runs fanless over -40 to 85°C.
Versalogic, a decades-old designer and manufacturer of x86-based single board computers for embedded and industrial applications, has posted preliminary product details for its first-ever Arm SBC. Referred to as “Tetra” (aka VL-EPC-2700), the new SBC puts NXP’s ubiquitous i.MX6 SoC to work on a rugged, fanless board that’s well endowed with networking, storage, graphics, USB, serial, and GPIO interfaces, and also supports modular expansion with mini-PCIe, mSATA, and microSD cards.

Interestingly, the Tetra board matches the 95 x 125mm footprint defined by the COM Express Basic computer-on-module specification. This design choice seems consistent with the company’s recent releases of a series of sandwich-style x86 SBCs, dubbed “Embedded Processing Units” (EPUs), that each combine a COM Express module with a same-sized carrier board. These have included the COM Express Compact (95 x 95mm) sized Raven and Condor, and the COM Express Basic (95 x 125mm) sized Blackbird (pictured to the right).

Versalogic’s embrace of Arm follows similar migrations by several other long-term makers of x86-based SBCs aimed at industrial, embedded, and IoT applications. Examples include the Micro/sys RCB1626, the WinSystems SBC35-C398, and the Diamond Systems Quantum SBC.
