Abstract: Techniques are provided for multiple device Peripheral Component Interface Express (PCIe) card having a single slot connector and each device interfaces with the single slot connector using distinct, unshared, data lane terminals of the single slot connector. In an example, a PCIe card can include a first device mounted to a circuit board and a second device mounted to the circuit board. The first device can be connected to a first plurality of data lane terminals of a single slot connector of the circuit board. The second device can be connected to a second plurality of data lane terminals of the single slot connector. The first plurality of data lane terminals can be distinct from the second plurality of data lane terminals.
