1. Introduction:
Offering the choice of a VIA Eden™ ESP processor for fanless systems with power sensitive
requirements, or a VIA C3™ E-Series processor for more multimedia rich applications, the highly
integrated VIA EPIA Mini-ITX mainboard features integrated 3D graphics, AC'97 audio, Ethernet,
USB and TV-Out connectivity. Measuring only 170mm x 170mm, it is the perfect platform for
developing the next generation of small footprint Digital Information Appliances and Entertainment
Devices.
This document is intended for System Integrators and design engineers designing or assembling
systems based around the VIA EPIA Mini-ITX mainboard.
