    With the launch of the 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.

     

    And here is the discussion from the Raspberry Pi Foundation about the CM4:

     

    And here is our introduction to the CM4, a comparison to CM3+, Raspberry Pi 4B, the CM4 IO board, and also Antenna Kit:

    Compute Module 4 is officially launched on 19th October 2020 with the same or better spec, and there are 32 variants of the module to choose from. This product page lists Compute Module 4 which comes WITH Wireless (WiFi and Bluetooth), 8GB RAM, 8GB eMMC, and the kits

    The Raspberry Pi Compute Module 4 (CM4) and Compute Module 4 Lite (CM4Lite) are loosely based on the Raspberry Pi 4 Model B. The CM4 has an option for cost-sensitive applications to be supplied without the eMMC fitted; this version is called the CM4Lite. The form factor of the new CM4 and CM4L is different from previous Compute modules, which have all shared a form factor. The change is due to the addition of new interfaces; a second HDMI, PCIe, and Ethernet. The addition of these new interfaces, especially PCIe, would not have been possible while preserving the older form factor. Instead, the electrical interface of the CM4 is via two 100-pin high-density connectors. While the switch to a newer form factor has allowed a reduction in the footprint. The total footprint of the CM4, including the socket, is smaller with the new form factor design.

    The back of CM4. The electrical interface of the CM4 is via two 100-pin high-density connectors at the back of the PCB.

     

    Here is the top view of CM4 with Wireless and onboard eMMC:

    Other Accessories:

    Full-Size HDMI Cable

    Raspberry Pi Compute Module 4 extended all the peripheral pins via the two 100-pin connectors, including the HDMI ports. The carrier boards that are bundled in the kits extend the HDMI to a full-size HDMI port and you might need this cable. The HDMI port is capable of delivering 1 x 4Kp60 or 2 x 4Kp30 multimedia. Do get it separately if you do not have one.

    External Dual Band (2.4 & 5GHz) Antenna Kit

    Since you opt for CM4 with built-in Wireless and there is a U.FL connector for external Antenna (software switchable to use PCB antenna or external antenna), you might want to check out this Antenna kit or Compatible dual-band Antenna for CM4 too, which supports dual-band WiFi and the Bluetooth:

     

     

     

    USB Devices Not Working?

    By default, the USB 2.0 hub on CM4 IO Board and the Carrier Board is disabled in the Raspberry Pi OS, this is to save power. So you will need to edit a file in the eMMCin order to enable the USB ports on the board. Else, the USB keyboard or mouse will not be able to function, so don't be surprised.

    To enable the USB 2.0 ports on the Compute Module 4, you need to edit the boot config file (/boot/config.txt) and add:

    dtoverlay=dwc2,dr_mode=host

    Then reboot the Pi. Now you should be able to use the built-in USB 2.0 ports!

    Note: Do follow the guide by Jeff Geerling in his video or blog post, you should be able to get the CM4 with eMMC boot up successfully.
