In computer design,Pico-ITX is a PCmotherboard form factor announced byVIA Technologies in January 2007 and demonstrated later the same year atCeBIT. The formfactor was transferred over toSFF-SIG in 2008. The Pico-ITX form factor specifications call for the board to be 10 × 7.2 cm (3.9 × 2.8 in), which is half the area ofNano-ITX.
The first motherboard produced in this form factor is calledEPIA PX10000G. It is 10 × 7.2 cm (3.9 × 2.8 in) and theprinted circuit board is 10 layers deep. Theoperating temperature range is from 0 to about 50 °C (32 to about 122 °F). Theoperating humidity level (relative and non-condensing) can be from 0% to about 95%. It uses a 1 GHz VIA C7-M processor, a VIAVX700 chip set, and isRoHS compliant.
It has onboardVGA video, VIA VT6106S 10/1008P8CEthernet,UDMA 33/66/100/133 44-pinATA (1x), andSATA (1x)I/O.DVI and LVDS video-out,USB 2.0,COM,PS/2 Mouse & Keyboard, andHD 5.1 channel audio (supplied by a VIA VT1708A chip) are supported through the usage of I/Opin headers and add-on modules/daughter cards.[1][2][3]
It has been demonstrated runningMicrosoftWindows XP andWindows Vista. older versions of majorLinux distributions, includingFedora Core 6 andUbuntu 7.10, will also run on it.[4] It is available as a single board, as well as part of a barebones package, theArtigo, asmall form factor complete computer.
This model is similar to the PX10000G, but uses the 500 MHzVIA EdenULV CPU.
There are two versions of this model, the PX5000G, which has a fan-assisted heatsink, and the PX5000EG, which has a fanless heatsink.
(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 daughtercard supplies access to:
The VIA VT1625M daughtercard supplies access to:
The Serener PXFPIO (also labeled under VIA PX-DIO) is 109mm × 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:
The VIA PX-TC daughter card, compatible with the PX10000G only, is designed to enhance the multimedia capture and output. It supplies access to:
The second motherboard series in this form factor, the P700 series improves upon the PX10000G series by offeringGigabit Ethernet (Using the VIA VT6122 chipset) or a 10/100 Ethernet adapter (VIA VT6107) as a manufacturing option, integrating the power adapter (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:
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.
The P700 comes retail with the P700-A & P700-B daughter cards.[9]
The P700-A supplies:
The P700-B supplies:
Even though the form factor was introduced byVIA Technologies, there are also boards available based onIntel processors. Some have theCPU and thechipset directly on the Pico-ITX board.
Pico-ITX boards are also available withARM architecture. In this field DH electronics uses the standardized DHCOM Computer On Modules with several ARM based modules.
ThePico-ITXe specification adds onto the Pico-ITX form factor by taking the EPIA-P700 and upgrading the chipset to aVX800, doubling the maximum RAM to 2 GB, allowing for 667/533 SO-DIMM RAM, upgrading the GPU to VIA'sChrome9 HC3, and adding support forSUMIT. Another notable addition is the expansion from 10 to 12 layers thickness.
