Rugged Bay Trail boardset offers dual GbE and dual mini-PCIe

Oct 27, 2016 — by Eric Brown — 854 views

VersaLogic’s rugged, sandwich-style “Raven” SBC offers a “Bay Trail” Atom, wide-range power, dual GbE ports, and multiple USB, serial, and mini-PCIe links.

Like Versalogic’s BayCat, Bengal, Hawk, and Osprey SBCs, the Raven runs Linux on a “Bay Trail” Atom E3800. It also similarly supports -40 to 85°C temperatures, offers shock and vibration resistance per MIL-STD-202G, and features a wide-range power input that supports automotive applications. It also supports military, avionic, and medical applications.

Like the Hawk and the Osprey, the Raven is not a true single board computer in that it uses VersaLogic’s sandwich style, 95 x 55 x 27mm “Embedded Processing Unit” (EPU) form factor. EPU boardsets are built from a COM Express Mini computer-on-module, an I/O-oriented carrier board, and a heat spreader plate for efficient thermal transfer. Presumably, the Raven uses the same VersaLogic VL-COMm-33 module used by the Osprey, as it is the only COM Express Mini with Bay Trail Atoms in the company’s arsenal.

The Raven and Osprey share the same single, dual, or quad-core Atom E3800 choices and similarly offer 2GB or 4GB (E3845 only) of soldered DDR3L. The Raven also has the same microSD slot, up to 8GB eMMC, and single SATA connection, in this case SATA 3.0 instead of 2.0.

Instead of full- and half-size mini-PCIe slots, the Raven offers two full-size slots, one of which supports mSATA. As before, a wide range of wireless and I/O mini-PCIe expansion modules are available.

The Raven has a single mini-DisplayPort++ instead of two standard mini-DisplayPorts, and similarly offers single-channel 18/24-bit LVDS. Other similar features include dual GbE ports, a USB 3.0 port, four USB 2.0 ports, 8x DIO, 3x timers, and I2C.

New features include the addition of two more RS-232/422/485 ports for four overall, as well as an 8-channel, 12-bit analog input, and a standard Trusted Platform Module (TPM) security chip. The Raven also has a wider range power supply of 8-30V, making it compatible with 12 or 24V vehicle applications. The new features have added to the weight — the Raven is 200 grams instead of the Osprey’s 140.

In addition to the industrial temperature support and shock and vibration, the Raven offers protection against damaging transient voltages, over voltage, and RF intrusion. The device supports Linux, Windows, Windows Embedded, and VxWorks, and offers five-year availability.

Further information

The Raven is now in stock at both VersaLogic and Digi-Key Corp. OEM quantity pricing starts at $854 for the single-core model with 2GB RAM. More information may be found at VersaLogic’s Raven product page and Raven announcement.
