1. Product Overview
Product OverviewProduct Overview
Product Overview
The VIA EPIA-P910 Pico-ITX mainboard is a com act native x86 mainboard o timized for systems in
embedded and multimedia a lications. It can also be used for various domain a lications such as medical
PC, industrial PC, and etc. The mainboard is based on the VIA VX11H Media System Processor that features
the VIA Chrome
™
640 DX11 with 2D/3D gra hics and video accelerators for rich digital media erformance.
The VIA EPIA-P910 mainboard has integrated HDMI
®
ort, Gigabit Ethernet (RJ-45) ort, USB 3.0 orts, VGA
connector, and onboard in header connector for o tional EPIA-P910-A ex ansion card.
The VIA EPIA-P910 has a owerful, secure, and efficient VIA Eden
®
X4 rocessor. The VIA Eden
®
X4
rocessor includes the VIA AES Security Engine, VIA CoolStream
™
Architecture and VIA PowerSaver
™
Technology.
The VIA EPIA-P910 includes one 1333 MHz DDR3 SODIMM slot that su ort u to 8 GB memory size. The
VIA EPIA-P910 rovides su ort for high fidelity audio with its included VIA VT2021 High Definition Audio
codec. In addition it su orts two SATA 3.0 Gb/s storage devices and fully com atible with Microsoft
®
and
Linux o erating systems.
1.1. Key Features and Benefits
1.1.1. VIA Eden
®
X4 Processor
The VIA Eden
®
X4 is a 64-bit su erscalar x86 multi-core rocessor combine on two dies. It is based on
advanced 28 nanometer rocess technology acked into an ultra com act NanoBGA2 ackage measuring
21mm x 21mm. The VIA Eden
®
X4 rocessor delivers a su erb erformance on multi-tasking, multimedia
layback, roductivity and internet browsing in a low ower budget. In addition, it is ideal for most of multi-
dis lay environment, and embedded system a lications such as industrial PCs, test machines, measuring
equi ment, digital signage, medical PCs, monitoring systems, gaming machines, in-vehicle entertainment, etc.
1.1.2. VIA VX11H MSP Chi set
The VIA VX11H is the fourth generation, highly integrated Media System Processor which rovides high
quality digital video streaming and high definition video layback. It features the VIA Chrome
™
640 DX11
2D/3D gra hics and video rocessor, High Definition video decoder su orts DDR3 1333 controller and USB
3.0 interface.
The VIA VX11H offers su erb-gra hics erformance, immersive visual ex erience, and su orts DirectX 11.0
that allows realistic 3D rendering and increased visual acuity. The VIA VX11H is based on a highly
so histicated ower efficient architecture that enables such rich integration into a com act ackage.
1.1.3. Ex ansion O tion
The EPIA-P910 further roves its versatility by roviding an o tional ex ansion connector. The EPIA-P910-A
I/O ex ansion card is connected through onboard in headers carrying the front anel I/O such as audio jack,
USB 2.0 orts, LED indicator and ower button.
The com anies using the EPIA-P910 with EPIA-P910-A I/O ex ansion card obtain the maximum benefits and
enable to slowly roll out u grades as necessary instead of having to re lace everything all at once.

Note:
As the o erating tem erature rovided in the s ecifications is a result of the test erformed in VIA’s chamber, a
number of variables can influence this result. Please note that the working tem erature may vary de ending on the
actual situation and environment. It is highly suggested to execute a solid testing and take all the variables into
consideration when building the system. Please ensure that the system runs well under the o erating tem erature in
terms of a lication.

2.2.2. SATA Connectors
The two SATA connectors onboard can su ort u to 3 Gb/s transfer s eeds. Both SATA connectors have a
7th in1 that can rovide +5V ower to a SATA Disk-on-Module (DOM). When a regular SATA hard drive is
connected, the 7th in
1
will be a ground in. The SATA connectors are labeled as “SATA1” and “SATA2”.
