Chassi kits for Em- ITX moterboards and I/O cards |
The Em-ITX form factor was introduced by VIA in 1998. Motherboards in Em-ITX are 17 cm x 12 cm placing Em-ITX in-between Mini-ITX and Nano-ITX in size. The form factor has input and output connectors placed along both long sides of the board and a possibility to expand the I/O interface using I/O cards. It's a route towards smaller designs without compromising functionality. Now there is also a series of chassi and development kits to develop embedded systems based on motherboards and I/O cards in Em-ITX. Front and rear panels are interchangeable and prepared with cut-outs to match board and card connectors. Heat sink, power supply and a selection of storage modules in separate chassis for docking are there to support the idea of modularity and scalability, from motherboards, I/O cards to complete embedded products for a range of markets segments. The EM-3110 I/O card is equipped with several audio and video interfaces for applications in Digital signage, Point-of-information and Gaming. The EM-3210 adds wireless interfaces to the ones already there on the motherboard to meet requirements in Transportation, Fleet management and Logistic applications. This concept is based on the EITX-3000 embedded motherboard which is equipped with the VIA Nano processor, 1.0 GHz to 1.3 GHz. The fact that connectors are lined up on two sides of the board leads to increased signal integrity since leaders and cables are shorter. The I/O interface targets applications with increased requirements on graphics and input/output richness and flexibility. |

EITX-3000 |
Embedded motherboard - Features |
• VIA Chrome9 HC3, DX9 3D/2D graphics,MPEG-2/4 and WMV9 decoding acceleration • Two single-channel LVDS display ports • Two Gigabit Ethernets • Two RS-232 and two RS-232/422/485 • Six USB ports • Em-IO expansion bus socket |
| |
The Em-IO expansion bus is a key feature in Em-ITX to add more I/O and adapt the interface to a variety of application requirements. The 160 pin socket includes signals for USB 2.0, GPIO, LPC, PCI Express, Display Output signals, ACPI 3.0, and 3.3V/5V/12V DC Power signals. Three I/O cards are offered. The I/O card is connected to the expansion bus. Each card targets requirements from a separate industrial market segment. |

| At this point the EITX-3000 embedded motherboard with a number of general I/O interfaces in the feature list is connected to an I/O card of choice to fit market requirements. For rapid development and faster time to market the offer includes chassi kits for each combination of the EITX-3000 motherboard and one of the three I/O cards. AMOS-5000 is the chassi kit for the EITX-3000 motherboard alone. |

Chassi Kit for motherboard |
|
|
AMOS-5000 |
AMOS-5000 is used with the EITX-3000 motherboard. The chassi and motherboard are designed to withstand shock, up to 50G, and vibration. Front and rear panels are interchangeable and possible to customize. |

Development Kits with motherboard and I/O Cards |
|
|
|
|
The three development kits, AMOS-5110, AMOS-5210 and AMOS-5430 are based on the EITX-3000 motherboard with the three I/O boards EMIO-3110, EMIO-3210 and EMIO-3430 respectively. The front and rear panels are interchangeable and have cutouts to meet the connectors on the motherboard and I/O cards. |
| |
Dockable subsystems |
| An additional subsystem enclosed in a chassi takes the concept of modularity and scalability one step further. It's designed to be docked on top of the main chassi and adds a 2.5 inch SATA hard disk drive to the system. |
| |
|
|
It's an option to dock the sub-system with a 2.5 inch hard disk drive on to the AMOS-5000, AMOS-5110, AMOS-5210 and AMOS-5430 series of chassi and development kits. |

Chassi kits for Mini-ITX and Nano-ITX motherboards |
| So far we have discussed the possibilities introducing flexibility in the design of an embedded system in the Em-ITX form factor. AMOS-1000 and AMOS-2000 is based on a similar concept for a number of embedded motherboards from VIA in the Mini-ITX and Nano-ITX form factors. A separate chassi with riser cards docked on the main chassi is the way to add features and I/O. The motherboard of your choice with riser cards with additional I/O in an adapted chassi is the fast route to complete an embedded system according to your taste. |

Conclusion |
| This modular and scalable concept from motherboards to I/O boards and riser cards in system chassis and docked subsystems is the fast track from idea to product. There are a number motherboards with various processors, chipsets and interface options to choose from. Features needed, but not there in the feature list, is simply added to the design in the form of I/O cards, riser cards and additional storage memory either in a sub-system or in the main chassi with the motherboard.
