Versalogic introduced its Swordtail VL-EPC-2702 as part of a product series of ARM‑based embedded computers. It comes with an ISO 11898‑2‑compliant CAN Bus interface, which supports the 29-bit identifier extended frame format (CAN 2.0B) for SAE J1939 applications.
Available with either the NXP i.MX6 Quad (quad-core), or the i.MX6 Duallite (dual-core) processors, the board carries an onboard Wi‑Fi, Bluetooth, and a socket for plug‑in cellular radios. The latest model adds built-in eMMC storage functionality. Designed for hostile environments, the 95 mm x 95 mm (3.7" x 3.7") computer board is rated for operation at industrial temperature range -40 °C to +85 °C. The model incorporates soldered-down 8 GiB eMMC Flash as a bootable onboard storage medium plus a micro‑SD socket that is included in all models of the series.
The boards are suitable for transmitting maintenance or diagnostic information without the need for a wired connection. Wi‑Fi and Bluetooth radios are onboard, and a Nimblelink Skywire socket supports a range of cellular and wireless plug-ins. The embedded computer boards are suitable for industrial, smart city, and transportation applications.
The devices feature soldered-on memory and a variety of I/O ports, including CAN Bus, wireless interfaces, Gigabit Ethernet with network boot capability, USB 2.0, serial I/O (EIA-232), and I²C interface. Also, MCOTS versions can hold up to 32 GiB of onboard flash storage. The product meets MIL‑STD‑202H specifications for impact and vibration. CAN Bus cables are included in the scope of delivery (2 mm 4‑pin to 2 mm 4‑pin Microclasp, 1 mm, and 2 mm 4‑pin Microclasp to DB9 connector).
