
Do not use wire smaller than 22 AWG. Use high quality UL 1007 compliant stranded
wire.

The length of the wire should not exceed 18 inches.

Avoid using any additional connectors in the power delivery system.

The power and ground leads should be twisted together, or as close together as possible
to reduce lead inductance.

A separate conductor must be used for each of the power pins.

All power input pins and all ground pins must be independently connected between the
power source and the power connector.

Use a high quality power supply that can supply a stable voltage while reacting to widely
varying current draws.

CPU

The Intel Atom E38xx SoC features integrated 3D graphics, video encode and decode, and
memory and display controllers in one package.

System RAM

The Hawk has soldered-on SDRAM with the following characteristics:

Memory Type: DDR3L

Data Rate: 1333 MT/s

Storage Capacity: 2 GB or 4 GB
o VL-EPU-3310-EAP: 2 GB
o VL-EPU-3310-EBP: 2 GB
o VL-EPU-3310-EDP: 4 GB

Flash Storage

The Hawk has the following Flash storage capabilities:

One microSD socket that supports microSD cards up to 32 GB

One Mini PCIe/mSATA socket

On-board eMMC Flash
o VL-EPU-3310-EAP: none
o VL-EPU-3310-EBP: 4 GB
o VL-EPU-3310-EDP: 8 GB

Real-Time Clock (RTC)

The Hawk features a real-time clock/calendar (RTC) circuit. The Hawk supplies RTC voltage in
S5, S3, and S0 states, but requires an external +2.75 V to +3.3 V battery connection to pin 7 of
the J1 power connector to maintain RTC functionality and RTC CMOS RAM when the Hawk is
not powered. The RTC can be set using the BIOS Setup program.
