# IndustrialPCI

PCI=Peripheral Component Interconnect.
IndustrialPCI is a version of PCI adapted for industrial and/or embedded applications.

The IPCI connector has three parts:

- Optional 60 pin PCI 64 bit extension (Top)
- Mandatory 120 pin PCI 32 bit (Middle)
- Optional 60 pin Custom I/O (Bottom)

(at the backplane)
(at the device (card))

UNKNOWN CONNECTOR at the backplane.
UNKNOWN CONNECTOR at the device (card).
