Versalogic Owl Small Form Factor Apollo Lake Embedded Computer Targets Military & Industrial Applications

VersaLogic Owl VL-EPU-4012 Embedded System Computer 

In October 2019 we reported on the VersaLogic Harrier computer that was slightly bigger than a credit card. Just announced by the company is a new embedded computer system is being developed, the Owl.

Basics of the VersaLogic Owl

The intended uses are again industry and military-grade applications. The system uses ECC memory and the Embedded Processing Unit (EPU) format. The processing unit is an Intel Atom E39xx Platform,  5th Gen Apollo Lake processor with dual or quad-core options.

Strength and Resilience

The ECC memory is fixed to the board and can be up to 8 GB in size. This reduces the damage that can be caused by vibration and shock, making the system tough and resilient.

Available Ports and Security

Hardware-based security is through a TDM 2.0 chip. There are onboard power conditioning, mini-PCIe expansion sockets, analog inputs, standard USB 3.0 and 4x 2.0 host ports and Ethernet I/O ports.

Form Factor of the Owl

The size is comparable to other small form factor models in the VersaLogic family of embedded systems computers. This board measures 95 x 95 x 27 mm (3.74 x 3.74 x 1.08″) and weighs just 200 grams.

Production Lifecycle and Industrial Environments

The temperature range is -40ºC to +85ºC capturing the industrial operation ranges for uses in many applications. The Owl is designed for a 10+ year production life cycle.

Custom Attributes

VersaLogic is making the Owl available to have modifications in off-the-shelf customization options such as labeling, conformal coating, revision locks, and customized testing and screening.
