Ultra Rugged Intel Atom "Apollo Lake" Embedded Processing Unit (EPU)

The Owl (VL-EPU-4012) is a small, rugged board-level embedded computer designed by VersaLogic, and is supported by their industry leading 10+ year product life support program.

Approximately four inches square and one inch thick, the Owl is a compact system featuring TPM security, a dual or quad core Intel Apollo Lake processor, and extensive on-board I/O including dual Gigabit Ethernet, USB 3.0 and 2.0 ports, serial ports, and analog inputs. A SATA interface, eMMC Flash options, and a microSD socket provide a range of data storage options, and dual Mini PCIe sockets accommodate a wide range of plug-in accessory cards.

Up to 8 GB of soldered-on Error Correcting Code (ECC) memory is available for high-reliability applications. ECC memory is beneficial in environments where single bit memory errors may occur, such as cosmic ray interactions which increase dramatically with altitude. 

For use in extremely hostile environments, the Owl has been designed and tested for full industrial temperature operation (-40° to +85°C) and meets MIL-STD-202H specifications for shock and vibration.
