Via Nano board in Em-ITX format

11 November 2009 Electronics Technology

The VIA EITX-3000 from VIA Technologies is an Em-ITX board designed for ultra-thin, high-performance, fanless embedded systems at temperatures ranging from -10°C to +70°C.

The board places the energy-efficient VIA Nano processor and VIA VX800 media system processor on the reverse side of the board, making greater real-estate available for passive cooling apparatus and thus negating the need for system fans. This makes it a good choice for systems in always-on applications such as high-end POS, kiosk, ATM, HMI, factory automation, POI and digital signage.

The EITX-3000 is powered by a choice of the latest 1,0 GHz or 1,3 GHz VIA Nano processor, supporting up to 2 GB of compact DDR2 SO-DIMM system memory. It includes an onboard DC-DC converter which supports both AT and ATX modes, configurable via an onboard switch. The VX800 media system processor takes advantage of the integrated VIA Chrome9 HC3 DirectX 9.0c compliant graphics and video controller, which includes MPEG-2, MPEG-4 and WMV9 hardware decoding acceleration for smooth media playback across multiple displays.

Dual, onboard LVDS ports support two 24-bit single channel interfaces with panel resolutions of up to 1280 x 1024. Both LVDS ports can offer independently configured resolutions and refresh rates in combination with an onboard VGA port supporting resolutions up to 1920 x 1440.

Networking includes dual VIA Velocity VT6130 Gigabit Ethernet controllers via two RJ45 ports, supporting Wake On LAN and PXE features. Storage support includes two onboard SATA ports and one compact Flash socket with HD audio provided through the VIA Vinyl VT1708B HD audio codec. Two USB 2.0 ports are provided on front panel I/O with an additional four available via pin headers.

Four flexible onboard serial ports include support for two RS232/422/485 ports, selectable without jumpers through the BIOS, while a PS/2 compatible bidirectional parallel port is available through pin headers. Status lights include power and HDD activity. A programmable watchdog timer is also included.
