Pico-ITX is a PC motherboard form factor announced by VIA Technologies in January 2007 and demonstrated later the same year at CeBIT. The formfactor was transferred over to SFF-SIG in 2008. The Pico-ITX form factor specifications call for the board to be 10 x 7.2 cm (3.9 x 2.8 in), which is half the area of Nano-ITX. The processor can be a VIA C7 or a VIA Eden V4 that uses VIA's NanoBGA2 technology for speeds up to 1.5 GHz, with 128KB L1 & L2 caches. It uses DDR2 400/533 SO-DIMM memory, with support for up to 1GB. Video is supplied via AGP by VIA's UniChrome Pro II GPU with built-in MPEG-2, 4, and WMV9 decoding acceleration. The BIOS is a 4 or 8 Mbit Award BIOS.[1][2][3]

EPIA PX
PX10000G
The first motherboard that was produced in this form factor is called EPIA PX10000G. It is 10 x 7.2 cm (3.9 x 2.8 in) and 10 layers deep. The operating temperature range is from 0°C to about 50°C. The operating humidity level (relative and non-condensing) can be from 0% to about 95%. It uses a 1 GHz VIA C7-M processor, a VIA VX700 chip set, and is RoHS compliant.
It has onboard VGA video-out, VIA VT6106S 10/100 RJ45 Ethernet, UDMA 33/66/100/133 44-pin PATA (1x), and SATA (1x) I/O. DVI and LVDS video-out, USB 2.0, COM, PS/2 Mouse & Keyboard, and HD 5.1 channel audio (supplied by a VIA VT1708A chip) are supported through the usage of I/O pin headers and add-on modules/daughter cards.[2][4][5]
It has been demonstrated running Microsoft Windows XP and Windows Vista. Modern versions of major Linux distributions, including Fedora Core 6 and Ubuntu 7.10, will also run on it. [6]
PX5000
This model is similar to the PX10000G, but uses the 500 MHz VIA Eden ULV CPU.
There are two versions of this model, the PX5000G, which has an active (fan-assisted) heatsink, and the PX5000EG, which has a passive (fanless) heatsink.
Add-on Modules
(Note: Either the VIA PX-O add-on module or 4 USB 2.0 I/O are supplied in retail packages.)
The VIA PX-O daughter card supplies access to:
- 1 RCA-out for S/PDIF usage
- 4 USB 2.0 ports
- 1 3.5mm Mic-in, 1 3.5mm Line-out, 1 3.5mm Line-in
- 1 Buzzer/speaker
- 1 CN9 Connector (function TBC)
- 1 CN10 Connector (function TBC).[7]
The VIA VT1625M daughter card supplies access to:
- 1 External TV-Out
- 1 Video Capture Port.[8]
The Serener PXFPIO (also labeled under VIA PX-DIO) is 109mm x 22mm in size and connects via a 120mm ribbon cable through a daughter card. This addon may require modification to the heatsink due to the size of the daughter card. It supplies access to:
- Power & Reset switches
- 3.5mm Audio in/out
- S/PDIF-in
- Power & HDD activity LEDs
- 4 USB 2.0 ports [9][10]
The VIA PX-TC daughter card, compatible with the PX10000G only, is designed to enhance the multimedia capture and output. It supplies access to:
EPIA-P700
The second motherboard series in this form factor, the P700 series improves upon the PX10000G series by offering a Gigabit Ethernet (Using the VIA VT6122 chipset) or a 10/100 Ethernet adaptor (VIA VT6107) as a manufacturing option, integrating the power adaptor (allowing for direct +12V DC-In & enabling it to directly power SATA), and making the Ethernet & VGA ports optional via the P700-A daughter card.
Expanded functionality is offered via the following pin I/O:
- 1 LAN
- 1 VGA/DVI
- 1 COM Port
- 1 Audio pin connector for Line-out, Line-in, MIC-in
- 1 Front panel
- 4 USB 2.0
- 1 PS2 mouse/keyboard
- 1 LVDS
- 1 LPC/SM Bus/GPIO
The EPIA-P700-10L has a 1 GHz VIA C7 CPU.
The EPIA-P700-05LE has a 500 MHz VIA Eden ULV CPU and has a passive heatsink.
Add-on Modules
The P700 comes retail with the P700-A & P700-B daughter cards.[12]
The P700-A supplies:
- Gigabit Ethernet
- 1 VGA port
- 1 COM port
- DVI port via I/O cable
The P700-B supplies:
Pico-ITXe
The Pico-ITXe specification adds on to the Pico-ITX formfactor by taking the EPIA-P700 and upgrading the chipset to a VX800, doubling the maximum RAM to 2 GB, allowing for 667/533 SO-DIMM RAM, upgrading the GPU to VIA's Chrome9 HC3, and adding support for SUMIT. Another notable addition is the expansion from 10 to 12 layers thickness.
