The IOB33 PCIe and IO expansion board delivers a x1 or x4 PCI Express (PCIe) expansion link from a Trenton single board computer down to a PCIe expansion slot on a PICMG 1.3 PCI express backplane. The PCIe link width delivered by the IOB33 PCIe and IO expansion board depends on the architecture of the specific single board computer. This link expansion is useful in extending the I/O card interface capabilities of the rackmount computer system.

The IOB33 PCIe and IO expansion board is a dual-function board in that it replaces the previous IOB30 is an optional I/O expansion board. The IOB33 connects to the controlled impedance connector (P20) on a Trenton PICMG 1.3 single board computer to complement the advanced USB and SATA I/O capability of the SBCs. A combo I/O plate is provided with the IOB33 to support the board’s legacy PS/2 and RS232 serial communication ports. Interface headers are also available on the IOB33 PCIe and IO expansion board. The IOB33 is secured to the single board computer using the provided standoffs and IOB33 mounting hardware.
