PCIe/104 Type 2 Bus (CN1 - Top)
Connector
CN1
carries the signals of the PCIe/104 PCIe bus. These signals match definitions found in the
PCI/104-Express & PCIe/104 Specification Version 2.01 from the PC/104 Embedded Consortium. Table 30
lists the pinouts of the PC/104-Express bus connector.
WARNING
Not all PCIe cards are compatible with the PCIe/104 Type 2 connector. Be sure that all of the
boards attached to this bus are compatible before powering the system.
