The CDC (Communications Daughter Card) slot is an internal expansion slot found in modern ThinkPads.

It is not meant for customer upgrades.
Different CDC slots exist for different functions and different form-factor cards, so you cannot just install any CDC adapter into a CDC slot.

The types of CDC cards you can use in your system is dependent on the BIOS. If you insert a Bluetooth IV with 56K Modem from an R52 system (for instance) and place it into an R51 system which only had the Modem Daughter Card, the system refuses to boot up and displays Invalid Daughter Card.


Overview

Cards listed here have a 40pin proprietary connector carrying signals for PCI, AC97 and USB.

Guessed size is 60×40mm and they show those two diagonally screw holes.

Some USB-only daughter cards with 4 or a little more pins are listed here until they are grouped out/together. E.g. some Bluetooth cards have “memory stick” size, long and thinner (and only one screw hole).

Any other connectors/form factors? Mention connectors, size.
