Exposing every interface from Raspberry Pi Compute Module 4, the Compute Module 4 IO Board provides a development platform and reference base-board design for the most powerful Compute Module yet.

The Compute Module 4 IO Board is a development board for those who wish to make use of the Raspberry Pi in a more flexible form factor, intended for industrial applications. This replaces the previous Raspberry Pi Compute Module I/O Board V3).

This item is just the IO board and does not contain a matching Compute Module (you can pick one up here). While the Compute Module contains the guts of a Raspberry Pi 4 (1.2GHz, quad-core Broadcom BCM2837 processor), it does not have any easy-to-use ports for development. That's where this IO Board comes in!
