2 Thin Mini-ITX Internal
Electrical Interfaces
2.1 Common Connector List
A high level goal of this document is to enable interchangeability of chassis with
motherboards from different suppliers. A common set of minimum interface
connectors between the motherboard and chassis is required to achieve a true
building block model for system integrators. The below table outlines these
standardized connectors.

It is expected that a group of motherboard connectors will exit the system via the Thin
Mini-ITX I/O aperture per industry standards. An example set of external I/O that
could be found on a Thin Mini-ITX motherboard is:
DC Input
USB 2.0
USB 3.0
RJ-45 LAN
HDMI (in/out)
eSATA
