Note	① USB 3.0 is equivalent to USB 3.2 Gen1 ② There's PoE header only on the Raspberry Pi official IO board without PoE circuit, that means additional PoE module is required for the official IO board to enable PoE feature. Unless otherwise specified, the PoE feature here stands for integrating 802.3af-compliant PoE circuit (5V/2.5A).

Connecting with Compute Module 4

standard CM4 socket and color-coded Raspberry Pi 40PIN GPIO headersuitable for Compute Module 4 Lite/eMMC series module

Rich interfaces
