FUNCTIONAL DESCRIPTION

The ETX-NANO-104 is one of the smallest embedded motherboard systems and is designed to support the ACCES I/O line of USB and PC/104 I/O modules along with the high performance benefits of ETX. Featuring a motherboard/baseboard only 120mm across, the NANO right-angle mounted connectors include VGA, RS-232/422/485, four USB 2.0 ports, standard audio, PS/2 mouse and keyboard, and Ethernet. ACCES I/O's experience in providing OEMs with custom ETX baseboards is highlighted by this dense motherboard design. ACCES I/O is the first exclusively embedded I/O company in the U.S. to provide semi-custom ETX baseboards and is also recognized for its small form factor I/O boards such as its low-profile PCI, PC/104 and USB/104 products. By integrating its proven I/O designs with this new small motherboard expertise, ACCES I/O can provide the industry with compact ETX I/O baseboard solutions ideal for space-sensitive applications.

The ETX-NANO-104 is unique due to the capability of utilizing any embedded ETX CPU board that meets the ETX standard for its processing, while providing PC/104 I/O module expansion. Whether the application requires a high-end 1.8GHz Intel Pentium M, a fanless mid-range 800MHz Celeron M, or a very low wattage AMD LX800 processor, ACCES I/O can provide a system solution to match a customer's specific requirements. Although smaller than the EPIC embedded boards, the NANO still supports PC/104-Plus I/O modules in an upward stack. In addition to the rear motherboard I/O, the NANO has supplemental onboard I/O connectors for flat-panel support, IDE, Compact Flash, and an extra RS-232 serial port. Power can be provided to the NANO through a 12-pin micro-fit power connector with a cable adapter connected to any ATX power supply. For an external DC powered system, a PC/104 or internal DC-DC power supply from ACCES I/O can be mounted inside an enclosure.

The ETX-NANO-104 is the perfect product for users ranging from high-volume OEMs to small, simple evaluation/prototype systems. By combining the benefits of both the ETX and PC/104 standards, a more cost effective time to market is achieved no matter what the quantity. Large quantity OEMs can use the wide range of COTS PC/104 and ETX products for simple and easy prototyping and evaluation purposes. Once these prototypes have been approved, ACCES can quickly and easily manufacture the ETX baseboards necessary for these high-volume systems using our semi-custom ETX baseboard program. For embedded developers designing systems which may require smaller quantities, the ETX-NANO-104 is still the perfect solution. Now your next embedded system can include all the benefits of this combo motherboard. These benefits include the capability to easily choose and upgrade your ETX CPU and the high availability of COTS PC/104 modules. Your next system can have the best of both worlds. Once again, time to market is dramaticall y reduced and future upgrades are as easy as choosing a new ETX CPU and/or PC/104 module.

This embedded motherboard solution can be mounted into various custom chassis depending on the number of planned PC/104 I/O boards that are needed. Using PC/104 I/O modules stacked in the system, the NANO can function as a complete, small, self-contained data acquisition system. The NANO can also be used as a stand-alone computer and act as a small USB I/O server for external data acquisition and control products. For pure embedded applications, the tiny ETX-NANO-104 can be mounted inside OEM equipment for PC-based monitoring and control.
