2.3 I/O Shields
Two I/O shields are provided with the board:
• Half-height I/O shield
• Standard-height I/O shield
The half-height I/O shield allows access to all back panel connectors while being
specifically designed for thin mini-ITX chassis, compliant with version 2.0 of the Mini-
ITX Addendum to the microATX Motherboard Interface Specification.
The standard-height I/O shield provides access to all the same connectors as the half-
height I/O shield while being compatible with standard mini-ITX and microATX chassis.
In addition to the F-type pre-cut hole, the standard-height I/O shield also provides
pre-cut holes for user installation of two external wireless antennas for system
configurations with wireless PCI Express Mini Card solutions.
Figure 18 and Figure 19 are I/O shield reference diagrams.
