With the launch of Raspberry Pi 4 Model B (1GB, 2GB, 4GB) last year (2019) and the 8GB RAM version in May this year (2020), everyone has been asking for Compute Module 4. Now, the waiting is over.
Compute Module 4 is official launched on 19th October 2020 with the same or better spec, and there are 32 variants of the module to choose from. Since there are quite significant upgrades on Compute Module 4 compares to its predecessor (CM3 or CM3+), you will need a new IO board for it. This is the IO board designed by the Raspberry Pi team specifically for CM4:
The Raspberry Pi CM4 IO board is designed for the development of products using the Raspberry Pi Compute Module 4. In some situations, the CM4 IO board can be used directly in products. The CM4 IO board contains many of the interfaces that the Raspberry Pi 4B has, for general usage you should refer to Raspberry Pi 4B documentation. The significant difference to a Raspberry Pi 4B is the addition of a PCIe x1 socket. The CM4 IO board can be used as a reference design for examples of how to interface to the Raspberry Pi Compute Module 4.
This CM4 IO board supports all variants of the CM4 board, including the Lite version (without onboard eMMC). The CM4 should be stacked on the CM4 IO board's two connectors:
Two 100-pin high-density sockets for the CM4

CM4 IO board breakouts quite some extra peripheral ports if we compared it with Raspberry Pi 4 Model B:
Dual DSI and Dual CSI connectors on CM4 IO board
Note: The CSI on the CM4 IO board is compatible with the Raspberry Pi Zero CSI connector, so you can utilize the FFC/FPC cable for Raspberry Pi Zero to interface with the camera module.
Note: However, the DSI port on CM4 IO Board is NOT COMPATIBLE with the FFC cable for RPi Zero.
Note: If you get the CM4 with eMMC, this video and blog post by Jeff Geerling is helpful for you to flash the eMMC with the OS that you want:
