2.2.2.2 Add-in Card Connectors
The board has the following add-in card connectors:
• PCI Express x1: one PCI Express x1 connector. The x1 interface supports
simultaneous transfer speeds up to 250 MB/s of peak bandwidth per direction and
up to 500 MB/s concurrent bandwidth
• PCI Conventional (rev 2.3 compliant) bus: two PCI Conventional bus add-in card
connectors.
Note the following considerations for the PCI Conventional bus connectors:
• The PCI Conventional bus connectors are bus master capable.
• SMBus signals are routed to the PCI Conventional bus connectors. This enables
PCI Conventional bus add-in boards with SMBus support to access sensor data on
the desktop board. The specific SMBus signals are as follows:
⎯ The SMBus clock line is connected to pin A40.
⎯ The SMBus data line is connected to pin A41.
