LPC Connector
The Low Pin Count Interface was defined by Intel
®
Corporation to facilitate the industry’s tran-
sition towards legacy free systems. It allows the integration of low-bandwidth legacy I/O com-
ponents within the system, which are typically provided by a Super I/O controller. Furthermore,
it can be used to interface firmware hubs, Trusted Platform Module (TPM) devices and embed-
ded controller solutions. Data transfer on the LPC bus is implemented over a 4 bit serialized
data interface, which uses a 33MHz LPC bus clock. For more information about LPC bus refer
to the Intel
®
Low Pin Count Interface Specification Revision 1.1’. The table below indicates the
pin functions of the LPC connector.

Expansion Slots
PCI Express x16 Slot
Install PCI Express x16 graphics card, that comply to the PCI Express specifications, into the
PCI Express x16 slot. To install a graphics card into the x16 slot, align the graphics card above
the slot then press it down firmly until it is completely seated in the slot. The retaining clip of
the slot will automatically hold the graphics card in place.
PCI Slot
The PCI slot supports expansion cards that comply with PCI specifications. You can install a
PCI expansion card or a customized riser card designed for only 2 PCI slots expansion (for low
profile PCI card only) into the PCI slot.
PCI Express x4 Slot
Install PCI Express cards such as network cards or other cards that comply to the PCI Express
specifications into the PCI Express x4 slot.
Mini PCIe Socket (for KD330-Q170 only)
The full-size Mini PCIe socket supports USB/Mini PCIe/mSATA signals and is used to install a
Mini PCIe card. Mini PCIe and mSATA signals can be switched with a jumper.
