1. Product Overview
The EPIA-E900 is a highly integrated Pico-ITXe board powered by a 1.2GHz VIA Eden® X4 processor and VIA VX11H MSP chipset that delivers a high performance and rich multimedia features in an ultra-compact package for a wide range of embedded system applications such as industrial automation, transportation, medical, and infotainment.
The EPIA-E900 board is fully compatible with Microsoft® and Linux operating systems, and provides an impressive I/O such as COM ports, mini HDMI® port, Gigabit Ethernet ports, USB 2.0 ports, USB 3.0 ports, SATA connector for storage devices, and onboard MXM connector for an optional E900-A expansion card. In addition, EPIA-E900 also includes one DDR3 1333 SODIMM slot that support up to 8GB memory size.
1.1. Key Features and Benefits
1.1.1. VIA Eden
®
X4 Processor
The VIA Eden® X4 is a 64-bit superscalar x86 multi-core processor combine on two dies. It is based on advanced 28 nanometer process technology packed into an ultra compact NanoBGA2 package measuring 21mm x 21mm. The VIA Eden® X4 processor delivers a superb performance on multi-tasking, multimedia playback, productivity and internet browsing in a low power budget. In addition, it is ideal for most of multi-display environment, and embedded system applications.
Note:
For Windows 7 and Windows Server 2008 R2 users only: If the user encounters the issue such as the operating system recognizing the VIA Dual-Core CPU as two processors instead of one processor with two cores, Please download and install the hotfix released by Microsoft to address this issue. The downloadable hotfix is available at http://support.microsoft.com/kb/2502664
1.1.2. VIA VX11H MSP Chipset
The VIA VX11H is the fourth generation, highly integrated Media System Processor which provides high quality digital video streaming and high definition video playback. It features the VIA C-640 DX11 3D/2D graphics and video processor, High Definition video decoder supports DDR3 1333 controller and USB 3.0 interface.
The VIA VX11H offers superb-graphics performance, immersive visual experience, and supports DirectX
11.0 that allows realistic 3D rendering and increased visual acuity. The VIA VX11H is based on a highly sophisticated power efficient architecture that enables such rich integration into a compact package.
1.1.3. Expansion Option
The EPIA-E900 further proves its versatility by providing an expansion MXM connector for optional E900-A expansion card. The E900-A expansion card is carrying multiple expansion I/O such as audio jack, USB 2.0 ports, SATA connector, PCIe slot, LVDS panel connector, DisplayPort/HDMI port, DVP port and etc. The companies using the EPIA-E900 with E900-A expansion card obtain the maximum benefits and enable to slowly roll out upgrades as necessary instead of having to replace everything all at once.

3. Jumpers
Jumper Description
A jumper consists of pair conductive pins used to close in or bypass an electronic circuit to set up or configure particular feature using a jumper cap. The jumper cap is a small metal clip covered by plastic. It performs like a connecting bridge to short (connect) the pair of pins. The usual colors of the jumper cap are black/red/blue/white/yellow.
Jumper Setting
There are two settings of the jumper pin: “
Short
and
Open
”. The pins are “
Short”
when a jumper cap is
placed on the pair of pins. The pins are
”Open”
if the jumper cap is removed.
In addition, there are jumpers that have three or more pins, and some pins are arranged in series. In case of a jumper with three pins, place the jumper cap on pin 1 and pin 2 or pin 2 and 3 to
Short
it.
Some jumper size is small or mounted on the crowded location on the board that makes it difficult to access. Therefore, using a long-nose plier in installing and removing the jumper cap is very helpful.
Figure 25: Jumper settings example
Caution:
Make sure to install the jumper cap on the correct pins. Installing it in the wrong pin might cause damage and malfunction.

3.1. Clear CMOS Jumper
The onboard CMOS RAM stores system configuration data and has an onboard battery power supply. To reset the CMOS settings, set the jumper on pins 2 and 3 while the system is off. Return the jumper to pins 1 and 2 afterwards. Setting the jumper while the system is on will damage the mainboard.
Figure 26: Clear CMOS jumper diagram
Setting Pin 1 Pin 2 Pin 3 Normal (default) Short Short Open Clear CMOS Open Short Short
Table 18: Clear CMOS jumper settings
Note:
Except when clearing the RTC RAM, never remove the cap from the CLEAR_CMOS jumper default position. Removing the cap will cause system boot failure. Avoid clearing the CMOS while the system is on; it will damage the mainboard.

5.4. Installing into a Chassis
The EPIA-E900 can be fitted into any chassis that has the mounting holes compatible with the standard Pico-ITXe mounting hole locations. Additionally, the chassis must meet the minimum height requirements for specified areas of the mainboard.
5.4.1. Suggested minimum chassis dimensions
The figure below shows the suggested minimum space requirements that a chassis should have in order to work well with the EPIA-E900.
Figure 43: Suggested minimum chassis dimensions
Each side of the mainboard should have a buffer zone from the internal wall of the chassis. The two sides of the mainboard that accommodates the I/O coastline should have a buffer of 1.00mm. The two sides adjacent to the I/O coastline should have at least a 5.00mm buffer.
For the side that is close to the MXM connector, the buffer should be at least 152mm if the E900-A expansion card will be used.
Note:
The E900-A expansion card is for project based enquiries only. Please contact sales for detailed information.
