Note: The Compute Module is not included, please choose your preferred CM4 from here:
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 with PoE (Power Over Ethernet) capability.
This PoE CM4 IO board breakouts quite some extra peripheral ports if we compared it with Raspberry Pi 4 Model B:
CM4 socket - suitable for all variants of Compute Module 4
Power input - DC Barrel, accepting 7~36V wide-range power supply
Gigabit Ethernet connector - Gigabit Ethernet RJ45 with PoE support
USB SLAVE port - allows burning system image into Compute Module 4 eMMC variants
USB3.2 ports - 4 x USB 3.2 Gen1 ports, for connecting sorts of USB devices
HDMI ports - 2 x HDMI ports, supports dual 4K 30fps output
RTC - RTC battery holder allows RTC-related functions like wakeup, shutdown, reboot, and more
CSI Camera port - 2 x MIPI CSI camera ports
DSI DISP - 2 x MIPI DSI display port
FAN - for connecting cooling fan, allows speed adjustment and measurement
FAN power selection - 5V or 12V voltage to drive the fan
IO-VREF/PoE selection - CM4 IO logic level: 3.3V or 1.8V, PoE: enable (EN) or disable (DIS)
40PIN GPIO header, color-coded
CAM0 and DISP0 I2C bus - fit the jumpers when using CAM0 or DISP0
Misc configurations
Dual LED indicators -red: Raspberry Pi power indicator, green: Raspberry Pi operating status indicator
TF card slot (bottom side) - insert a Micro SD card with a pre-burnt system, to start up Compute Module 4 Lite
Note: The CSI on the PoE 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 PoE 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:
