3.19 PCI-Express

The CB3052 offers a 2x40pin custom connector for the PCI-Express bus. You can connect one PCIe4x

device here. Alternatively, up to four PCIe1x devices can be connected. Adapter cards featuring standard

PCIe sockets or a PCIe Mini Card connector are available. Please contact your sales representative for

these cards.
