Cautions
Electrostatic Discharge
CAUTION:
Electrostatic discharge (ESD) can damage circuit boards, disk drives, and other
components. The circuit board must only be handled at an ESD workstation. If an
approved station is not available, some measure of protection can be provided by
wearing a grounded antistatic wrist strap. Keep all plastic away from the board, and do
not slide the board over any surface.
After removing the board from its protective wrapper, place the board on a grounded,
static-free surface, component side up. Use an antistatic foam pad if available.
The board should also be protected inside a closed metallic antistatic envelope during
shipment or storage.

Note:
The exterior coating on some metallic antistatic bags is sufficiently conductive to cause
excessive battery drain if the bag comes in contact with the bottom side of the Owl.
Handling Care
CAUTION:
Avoid touching the exposed circuitry with your fingers when handling the board. Though
it will not damage the circuitry, it is possible that small amounts of oil or perspiration on
the skin could have enough conductivity to cause the contents of CMOS RAM to
become corrupted through careless handling, resulting in CMOS resetting to factory
defaults.
Earth Ground Requirement
CAUTION:
All mounting standoffs should be connected to earth ground (chassis ground). This
provides proper grounding for EMI purposes.

Introduction
Figure 1. The Harrier (VL-EPU-4011)
Features
The Harrier is an extremely small and rugged SWaP-optimized embedded computer. It
has been engineered and tested to meet the industry’s need for smaller, lighter and
lower power embedded systems. Slightly larger in size than a credit card and one inch
thick, the Harrier is a member of VersaLogic’s family of small, ultra-rugged embedded
x86 computers. Equipped with a powerful dual- or quad-core Intel “Apollo Lake”
processor and soldered-on ECC RAM, the Harrier is designed to withstand extreme
temperature, impact, and vibration.
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 with cosmic ray interactions which increase
dramatically with altitude.

Introduction
VL-EPU-4011 BIOS Reference Manual 8
A TPM 2.0 chip is included for hardware-based security.
On-board I/O includes dual Gigabit Ethernet, one USB 3.0 and four USB 2.0 ports, and
two serial ports. SATA interface, eMMC Flash options, and a microSD socket provide a
range of data storage options. Dual Mini PCIe sockets accommodate plug-in A/D, Wi-Fi
modems, GPS receivers, MIL-STD-1553, Ethernet, Firewire, and other mini cards.
The Harrier is designed and tested for full industrial temperature (-40º to +85ºC)
operation and meets MIL-STD-202H specifications for shock and vibration. It also
features an on-board voltage regulation for dependable operation from nominal 12V
sources.
