Pico-ITX board bears twins

Via Technologies has announced a third motherboard using its tiny 3.9 x 2.8 inch pico-ITX format. Available with a 1GHz C7 or 500MHz Eden ULV processor, the P700 boasts an onboard DC-DC adapter, and comes with two daughterboards that add real-world I/O connectors.

The Epia P700 is a follow-on to Via's PX10000G, the company's initial pico-ITX board that shipped in May 2007. Via's second pico-ITX effort was the PX5000EG, which moved to a 500MHz Eden ULV processor for passive cooling applications.

The new Epia P700 is available with the 1GHz Via C7 processor as the Via Epia P700-10L, or with the fanless 500MHz Eden ULV as the Epia P700-05LE. Both models include an integrated power adapter, enabling them to accept 12VDC power directly — and even power 5V SATA drives — without an external power daughterboard. Compared to the older pico-ITX products, other improvements include gigabit Ethernet, and bundled companion boards with real-world connectors.

The Epia P700 comes with P700-A and P700-B “companion boards” that fit atop the linear pin headers located at the left and right of the main board, as seen below. The P700-A provides an RJ45 connector for gigabit Ethernet, a VGA port, and a COM port, while P-700B sports four USB ports and three audio jacks. Other connectors on the Epia P700 include a 44-pin IDE connector, and a SATA connector.

Securely mounted, the P700's daughterboards can effectively be considered part of the main board. However, they do approximately double its width (overall system dimensions were not cited by Via). Alternatively, for installations where a small footprint is more important than overall system height, the companion boards could be mounted below the main board, given suitable cabling and mounting brackets.

As mentioned, the Epia P700 is offered with a choice of CPUs, both supported by Via's VX700, a core-logic chip that integrates the company's VN800 northbridge and VT8237 southbridge functionality. Graphics capabilities include 2D/3D graphics acceleration, MPEG2 support, and dual monitor outputs. Meanwhile, a single SODIMM socket accommodates up to 1GB of DDR2 533 SDRAM memory.

Via lists the following key features and specifications for the Epia P700 board:
