SODIMM-like COMs snap ARM SoCs into embedded apps

Mar 19, 2013 — by Rick Lehrbaum 2,025 views

Embedded board-maker Seco has rounded out a series of three SODIMM-like COMs (computer-on-modules) built to µQseven form-factor specifications. They’re based on three different ARM-powered system-on-chip (SoC) processors, from Nvidia, Freescale, and TI.

The three tiny Seco COMs are based on Nvidia’s Tegra T30, Freescale’s i.MX6, and TI’s OMAP5430, resulting in an interesting spectrum of capabilities. All three are built to the Qseven standard’s new reduce-sized “µQseven” form-factor, added as part of the Qseven v2.0 update last September.

Qseven is a free standard that defines board dimensions for standard Qseven (70 x 70mm) and µQseven (40 x 70mm) sized modules, connector pinouts, and various other requirements for snap-in modules, which interface to embedded application baseboards via a 230-pin MXM edgecard connector for interfacing with embedded application baseboards.
