1076 standard. 3U boards have a 110-pin connector (J1), which carries the 32-bit PCI bus signals, and an optional 110-pin connector (J2), which carries either user-defined I/O or the upper 32 bits of an optional 64-bit PCI bus. 6U cards have an identical J1, a J2 that is always used for 64-bit

The backplanes can be designed for 3.3 V VIO or 5 V VIO operation. These are differentiated by having 'Cadmium Yellow' coloured key for 3.3V or 'Brilliant Blue' colour for 5V operation. If the
CompactPCI card operates on a particular VIO voltage the card shall have the respective coloured

CompactPCI was initially ratified as PICMG 2.0 in late 1995 as a passive backplane for PCI signaling. The 2.x series of specifications from PICMG provide support for a variety of technologies including Hot Swap (PICMG 2.1), Telephony signaling (PICMG 2.5) and most notably the expansion of the

Originally designed to support the PCI signaling protocol (and hence the name "CompactPCI"), CompactPCI has grown to include a variety of technologies centered on the application of the 2mm HM connector on the 3U and 6U form factor. In fact many systems are implemented with no PCI bus on the

CompactPCI. Some of the pins are slightly longer to provide proper grounding when devices are inserted and removed.
