Open-Q™ 820 Development Kit

3.8.19 PCI Express 1X Slot J30

The PCI Express slot (J30) used on the Open-Q 820 development kit is a standard PC style half-height card
slot. It allows for external peripheral connectivity such as Gigabit Ethernet, Gigabit Wi-Fi, or PCIe based audio
/ video processors. Since there is no native Ethernet connectivity on the Open-Q platform, an off-the shelf
PCIe based Ethernet card can be used here. Please check the software compatibility before connecting the
PCIe Ethernet card. In addition to being able to establish external connectivity, the connector provides access
to the PCIE2 interface, which is routed from the SOM.

3.8.20 Mini PCI Express Connector J72

The Open-Q 820 development kit also supports the use of a PCI Express mini card. The primary difference
between a PCI Express 1X card and a PCI Express mini card is the unique form factor optimized for mobile
computing platforms. In addition to that, the mini card is optimized for communication applications. Similarly,
the PCI Express mini card allows for external peripheral connectivity such as Ethernet and wireless
connectivity as well as acting like a modem.
The Mini PCI Express connector J72 used on the Open-Q 820 development kit supports both the standard full
and half size PCI Express mini card. Depending on the size of card used, user can utilize the 4 mounting
holes below connector J72 to secure the card in place. Figure 22 depicts these mounting holes. Please check
the software compatibility before connecting any PCI Express mini cards.
Note: The pin-outs of this connector comply with the PCI Express mini card standards. Please refer to the
