3. COM Express Pinouts and Signal Descriptions
The following information is a summary of the most important information regarding pinout and signal description in the official PICMG
COM.0 Rev 2.0 (soon 2.1)
The pinout is noted here to emphazise issues that have not been followed in the past. The following might have small inacuaracies so in
case of doubt the offical design guide of PICMG should be consulted.
3.1. AB/CD Pin Definitions
The Express-CVC is a Type 2 module supporting PCI and PATA IDE on the CD connector.
All pins in the specification are described including those not supported on the Express-CVC.
Those not supported on the Express-CVC module are crossed out
