Product Overview

The VIA EPIA-M860 Mini-ITX mainboard is an entry-level native x86 mainboard for systems in embedded and

multimedia applications. The mainboard is based on the VIA VX900 Unified Digital Media IGP chipset that features the

VIA C-9 HC with 2D/3D graphics and video accelerators for rich digital media performance.

The VIA EPIA-M860 includes a powerful, secure, and efficient VIA Nano™ processor. The VIA Nano processor includes

the VIA Padlock Security Engine, VIA CoolStream™ Architecture, VIA StepAhead™ Technology Suite, and VIA

TwinTurbo™ technology.

The VIA EPIA-M860 includes one 1066 MHz DDR3 DIMM slot that supports up to 4 GB. The VIA EPIA-M860 provides

support for high fidelity audio with its included VIA VT1708S High Definition Audio codec. In addition it supports two

SATA 3Gb/s storage devices.

The VIA EPIA-M860 is compatible with a full range of Mini-ITX chassis as well as FlexATX and MicroATX enclosures

and power supplies. The VIA EPIA-M860 is fully compatible with Microsoft

®

and Linux operating systems.

1.1. Key Features and Benefits

1.1.1. VIA Nano™ 1.2GHz Processor

The VIA Nano is a 64-bit superscalar x86 processor based on a 65 nanometer process technology. Packed into an ultra

compact NanoBGA2 package (measuring 21mm x 21mm), it delivers an energy-efficient yet powerful performance, with

cool and quiet operation. The VIA Nano is ideal for embedded system applications such as industrial PCs, test machines,

measuring equipment, digital signage, medical PCs, monitoring systems, gaming machines, in-vehicle entertainment, etc.

1.1.2. VIA VX900 Chipset

The VIA VX900 Unified Digital Media Chipset is designed to enable high quality digital video streaming and DVD

playback in a new generation of fanless, small form factor PCs and IA devices. The VIA VX900 features VIA C-9 HC3

with 2D/3D graphics and video acceleration, DDR3 1066/800 MHz support, motion compensation and dual display

support to ensure a rich overall entertainment experience.

1.1.3. Flexible Power Options

The VIA EPIA-M860 comes with two power input options: ATX and DC-in. The ATX version supports standard 20-pin

ATX power supply connectors. The DC-in version requires a 12V/5A max input. The AC/DC adapter can be purchased

as an option with the DC-in version. The DC-in version also has an onboard 4-pin power supply connector.

1.1.4. Modular Expansion Options

The VIA EPIA-M860 ensures long-term usability with its support for industry standard expansion options. Its support for

legacy PCI expansion cards helps to smooth and reduce the costs of transitioning to newer expansion technologies. The

VIA EPIA-M860 enables companies to slowly roll out upgrades as necessary instead of having to replace everything all

at once. This ensures that companies using the EPIA-M860 obtain the maximum benefits from its past investments in PCI

expansion cards.

The VIA EPIA-M860 also includes a 1-Lane PCI Express 2.0 expansion slot that provides protection against obsolescence.

The VIA EPIA-M860 further proves its versatility with its included Mini PCI Express slot. Companies can feel free to

design low-profile systems based on the versatile EPIA-M860.

Note:

As the operating temperature provided in the specifications is a result of the test performed in VIA’s chamber, a number of

variables can influence this result. Please note that the working temperature may vary depending 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 operating temperature in terms of application.
