1.1 CPU Board Overview
Figure 1-1: NANO-GX2
The EPIC form factor NANO-GX2 is a highly integrated CPU card for embedded
computers, specifically optimized for multi-media applications requiring minimum
installation space. The NANO-GX2 is particularly suitable for low power and fan-less
applications. The NANO-GX2 supports a full range of functionality for an
AT/ATX-compatible industrial computer in a space-saving 3.5” profile. The NANO-GX2 is
equipped with an on board low-power consumption and high performance AMD Geode™
GX 466 processor. The NANO-GX2 also includes 128 MB of DDR memory onboard.
1.1.1 Applications
The NANO-GX2 motherboard has been designed for thin client applications. The low
power consumption and embedded processor provide adequate computing power for
these applications. The fanless design ensures a quiet and more reliable computer setup.
1.1.2 Benefits
Some of the NANO-GX2 motherboard benefits include,
