Pico-ITX

Source: Wikipedia, the free encyclopedia.

In computer design, Pico-ITX is a PC

SFF-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 of Nano-ITX
.

PX10000G

The first motherboard produced in this form factor is called

RoHS
compliant.

It has onboard

daughter cards.[1][2][3]

It has been demonstrated running

Ubuntu 7.10, will also run on it.[4] It is available as a single board, as well as part of a barebones package, the Artigo, a small form factor
complete computer.

PX5000

This model is similar to the PX10000G, but uses the 500 MHz

ULV
CPU.

There are two versions of this model, the PX5000G, which has a fan-assisted heatsink, and the PX5000EG, which has a 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 daughtercard 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).[5]

The VIA VT1625M daughtercard supplies access to:

  • 1 external TV-out
  • 1 video capture port.[2]

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:

  • power & reset switches
  • 3.5mm audio in/out
  • S/PDIF-in
  • power & HDD activity LEDs
  • 4 USB 2.0 ports[6][7]

The VIA PX-TC daughter card, compatible with the PX10000G only, is designed to enhance the multimedia capture and output. It supplies access to:

  • 1 S-Video port
  • 1 video-in port
  • 1 YPbPr port
  • 1 S/PDIF-out[8]

EPIA-P700

The second motherboard series in this form factor, the P700 series improves upon the PX10000G series by offering Gigabit 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:

  • 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 (Unusable due to VIA not releasing a GPIO driver)

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.[9]

The P700-A supplies:

  • Gigabit Ethernet
  • 1 VGA port
  • 1 COM port
  • DVI port via I/O cable

The P700-B supplies:

  • 4 USB 2.0 ports
  • 1 Buzzer
  • 1 Line-out, 1 Line-in, 1 MIC-in (3.5 mm)[10][11]

Intel-based products

Even though the form factor was introduced by

CPU and the chipset
directly on the Pico-ITX board.

ARM-based products

Pico-ITX boards are also available with

ARM architecture
. In this field DH electronics uses the standardized DHCOM Computer On Modules with several ARM based modules.

Pico-ITXe

The

Chrome9 HC3, and adding support for SUMIT
. Another notable addition is the expansion from 10 to 12 layers thickness.
