The Open-Q 820 / 820Pro µSOM 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 / 820Pro µSOM
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. The figure below 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.
