The PCITX4-6 is a low profile right angle 32-bit PCI riser card that can turn in either direction and also fit into a 1U chassis. The overall dimension of the PCITX4-6 is 3.54"L X 0.96"H, the connector center height is 0.76".

When user's I/O board is inserted on A side, it will be parallel to the motherboard with component side up. When user's I/O board is inserted on A side, it will be parallel to the motherboard with component side up. When user's I/O board is inserted on B-side, it will be parallel to the motherboard with component side down.

Orientation for this riser card is interchangeable, for example if the user purchases a B-side 5-volt riser card (B5), the same riser card can also be used as an A-side 3.3V riser card (A3). This is achieved simply by turning the riser card around and plugging into the PCI slot facing the other direction.
