VIA EPIA-P820 Pico-ITX Board

Based on the VIA Nano® processor, the VIA EPIA-P820 offers customers a range of advantages over competitor offerings, including full 64-bit software support, and a high-performance superscalar architecture. The ultra compact VIA EPIA-P820 supports 2GB of DDR2 system memory and leverages a power-efficient, high performance 1.2GHz U2500 VIA Nano® E-Series processor to provide system developers with the most powerful Pico-ITX platform ever.


The product uses a specially designed I/O add-on-board which supplements the native HDMI port to add a VGA port, a Gigabit LAN port and two USB 2.0 ports. Other features include 6 channel high definition audio, and on-board pin headers that provide support for an additional four USB 2.0 ports, an LPC connector, SMBus connector, PS/2 support, audio jacks, LVDS, four pairs of DIO and two UART ports.

The advanced graphics of the VIA EPIA-P820 is delivered via the VIA VX855 media system processor with its support for a wide range of digital media technologies and I/O. Within the chipset the high performance VIA C-9 HCM IGP and allows for flawless playback of 1080p HD video at amazingly low processor utilization levels.
