NOTE Not all SDRAM/eMMC configurations are available. Please check with our sales team.
¹ In some applications PCIe Gen 3.0 is possible, but this is not officially supported.
Raspberry Pi Compute Module 4 compatibility
For most customers, Raspberry Pi Compute Module 5 will be pin-compatible with Raspberry Pi Compute Module 4. The following features have been removed/altered between the Raspberry Pi Compute Module 5 and Raspberry Pi Compute Module 4 models:
· Composite video – The composite output available on Raspberry Pi 5 is NOT routed out on Raspberry Pi Compute Module 5
· 2-lane DSI port – There are two 4-lane DSI ports available on Raspberry Pi Compute Module 5, muxed with the CSI ports for a total of two
· 2-lane CSI port – There are two 4-lane CSI ports available on Raspberry Pi Compute Module 5, muxed with the DSI ports for a total of two
· 2× ADC inputs
Ingatan
Raspberry Pi Compute Module 4s maximum memory capacity is 8GB, whereas Raspberry Pi Compute Module 5 is available in a 16GB RAM variant. Unlike Raspberry Pi Compute Module 4, Raspberry Pi Compute Module 5 is NOT available in a 1GB RAM variant.
Audio analog
Analogue audio can be muxed onto GPIO pins 12 and 13 on Raspberry Pi Compute Module 5, in the same way as on Raspberry Pi Compute Module 4. Use the following device tree overlay to assign analogue audio to these pins:

dtoverlay=audremap # or dtoverlay=audremap,pins_12_13
Due to an errata on the RP1 chip, GPIO pins 18 and 19, which could be used for analogue audio on Raspberry Pi Compute Module 4, are not connected to the analogue audio hardware on Raspberry Pi Compute Module 5 and cannot be used.
NOTE The output is a bitstream rather than a genuine analogue signal. Smoothing capacitors and an amplifier will be needed on the IO board to drive a line-level output.
Changes to USB boot
USB booting from a flash drive is only supported via the USB 3.0 ports on pins 134/136 and 163/165. Raspberry Pi Compute Module 5 does NOT support USB host boot on the USB-C port. Unlike the BCM2711 processor, the BCM2712 does not have an xHCI controller on the USB-C interface, just a DWC2 controller on pins 103/105. Booting using RPI_BOOT is done via these pins.
Change to module reset and power-down mode
I/O pin 92 is now set to PWR_Button rather than RUN_PG — this means you need to use a PMIC_EN to reset the module. The PMIC_ENABLE signal resets the PMIC, and therefore the SoC. You can view PMIC_EN when it’s driven low and released, which is functionally similar to driving RUN_PG low on Raspberry Pi Compute Module 4 and releasing it. Raspberry Pi Compute Module 4 has the added benefit of being able to reset peripherals via the nEXTRST signal. Raspberry Pi Compute Module 5 will emulate this functionality on CAM_GPIO1. GLOBAL_EN / PMIC_EN are wired directly to the PMIC and bypass the OS completely. On Raspberry Pi Compute Module 5, use GLOBAL_EN / PMIC_EN to execute a hard (but unsafe) shutdown. If there is a need, when using an existing IO board, to retain the functionality of toggling I/O pin 92 to start a hard reset, you should intercept the PWR_Button at the software level; rather than having it invoke a system shutdown, it can be used to generate a software interrupt and, from there, to trigger a system reset directly (e.g. write to PM_RSTC ). Device tree entry handling a power button (arch/arm64/boot/dts/broadcom/bcm2712-rpi-cm5.dtsi):
pwr_key: pwr { };
label = “pwr_button”; // linux,code = <205>; // KEY_SUSPEND linux,code = <116>; // KEY_POWER gpios = <&gio 20 GPIO_ACTIVE_LOW>; debounce-interval = <50>; // ms
Code 116 is the standard event code for the kernel’s KEY_POWER event, and there is a handler for this in the OS.
Raspberry Pi recommends using kernel watchdogs if you are concerned about the firmware or the OS crashing and leaving the power key unresponsive. ARM watchdog support is already present in Raspberry Pi OS via the device tree, and this can be customised to individual use cases. In addition, a long press/pull on the PWR_Button (7 seconds) will cause the PMIC’s built-in handler to shut down the device.
Detailed pinout changes
CAM1 and DSI1 signals have become dual-purpose and can be used for either a CSI camera or a DSI display. The pins previously used for CAM0 and DSI0 on Raspberry Pi Compute Module 4 now support a USB 3.0 port on Raspberry Pi Compute Module 5. The original Raspberry Pi Compute Module 4 VDAC_COMP pin is now a VBUS-enabled pin for the two USB 3.0 ports, and is active high.

Transitioning from Compute Module 4 to Compute Module 5
Raspberry Pi Compute Module 4 has extra ESD protection on the HDMI, SDA, SCL, HPD, and CEC signals. This is removed from Raspberry Pi Compute Module 5 due to space limitations. If required, ESD protection can be applied to the baseboard, although Raspberry Pi Ltd does not regard it as essential.

Papan Sirkuit Cetak
Raspberry Pi Compute Module 5s PCB is thicker than Raspberry Pi Compute Module 4s, measuring at 1.24mm+/-10%.
Track lengths
HDMI0 track lengths have changed. Each P/N pair remains matched, but the skew between pairs is now <1mm for existing motherboards. This is unlikely to make a difference, as the skew between pairs can be in the order of 25 mm. HDMI1 track lengths have also changed. Each P/N pair remains matched, but the skew between pairs is now <5mm for existing motherboards. This is unlikely to make a difference, as the skew between pairs can be in the order of 25 mm.

Transitioning from Compute Module 4 to Compute Module 5
Ethernet track lengths have changed. Each P/N pair remains matched, but the skew between pairs is now <4mm for existing motherboards. This is unlikely to make a difference, as the skew between pairs can be in the order of 12 mm.
Konektor
The two 100-pin connectors have been changed to a different brand. These are compatible with the existing connectors but have been tested at high currents. The mating part that goes onto the motherboard is Amphenol P/N 10164227-1001A1RLF.
Anggaran listrik
As Raspberry Pi Compute Module 5 is significantly more powerful than Raspberry Pi Compute Module 4, it will consume more electrical power. Power supply designs should budget for 5V up to 2.5A. If this creates an issue with an existing motherboard design, it is possible to reduce the CPU clock rate to lower the peak power consumption. The firmware monitors the current limit for USB, which effectively means that usb_max_current_enable is always 1 on CM5; the IO board design should take the total USB current required into consideration. The firmware will report the detected power supply capabilities (if possible) via `device-tree’. On a running system, see /proc/ device-tree/chosen/power/* . These files are stored as 32-bit big-endian binary data.

Software changes/requirements
From a software point of view, the changes in hardware between Raspberry Pi Compute Module 4 and Raspberry Pi Compute Module 5 are hidden from the user by new device tree files, which means the majority of the software that adheres to the standard Linux APIs will work without change. The device tree files ensure that the correct drivers for the hardware are loaded at boot time.
Device tree files can be found in the Raspberry Pi Linux kernel tree. For example: https://github.com/raspberrypi/linux/blob/rpi-6. 12.y/arch/arm64/boot/dts/broadcom/bcm2712-rpi-cm5.dtsi.
Users moving to Raspberry Pi Compute Module 5 are advised to use the software versions indicated in the table below, or newer. While there is no requirement to use Raspberry Pi OS, it is a useful reference, hence its inclusion in the table.

Moving to standard Linux APIs/libraries from proprietary drivers/ firmware
All the changes listed below were part of the transition from Raspberry Pi OS Bullseye to Raspberry Pi OS Bookworm in October 2023. While Raspberry Pi Compute Module 4 was able to use the older deprecated APIs (as the required legacy firmware was still present), this is not the case on Raspberry Pi Compute Module 5.
Raspberry Pi Compute Module 5, like Raspberry Pi 5, now relies on the DRM (Direct Rendering Manager) display stack, rather than the legacy stack often referred to as DispmanX. There is NO firmware support on Raspberry Pi Compute Module 5 for DispmanX, so moving to DRM is essential.
A similar requirement applies to cameras; Raspberry Pi Compute Module 5 only supports the libcamera library’s API, so older applications that use the legacy firmware MMAL APIs, such as raspi-still and raspi-vid , no longer function.
Applications using the OpenMAX API (cameras, codecs) will no longer work on Raspberry Pi Compute Module 5, so will need to be rewritten to use V4L2. Examples of this can be found in the libcamera-apps GitHub repository, where it is used to access the H264 encoder hardware.
OMXPlayer is no longer supported, as it also uses the MMAL API — for video playback, you should use the VLC application. There is no command-line compatibility between these applications: see the VLC documentation for details on usage.
Raspberry Pi previously published a whitepaper that discusses these changes in more detail: https://pip.raspberrypi.com/ categories/685-app-notes-guides-whitepapers/documents/RP-006519-WP/Transitioning-from-Bullseye-to-Bookworm.pdf.

Transitioning from Compute Module 4 to Compute Module 5
Informasi tambahan
While not strictly related to the transition from Raspberry Pi Compute Module 4 to Raspberry Pi Compute Module 5, Raspberry Pi Ltd has released a new version of the Raspberry Pi Compute Module provisioning software and also has two distro generation tools that users of Raspberry Pi Compute Module 5 may find useful. rpi-sb-provisioner is a minimal-input, automatic secure boot provisioning system for Raspberry Pi devices. It is entirely free to download and use, and can be found on our GitHub page here: https://github.com/raspberrypi/rpi-sb-provisioner. pi-gen is the tool used to create the official Raspberry Pi OS images, but it is also available for third parties to use to create their own distributions. This is the recommended approach for Raspberry Pi Compute Module applications that require customers to build a custom Raspberry Pi OS-based operating system for their specific use case. This is also free to download and use, and can be found here: https://github.com/RPi-Distro/pi-gen. The pi-gen tool integrates well with rpi-sb-provisioner to provide an end-to-end process for generating secure boot OS images and implementing them on Raspberry Pi Compute Module 5. rpi-image-gen is a new image creation tool (https://github.com/raspberrypi/rpi-image-gen) that may be more appropriate for more lightweight customer distributions. For bring-up and testing — and where there is no requirement for the full provisioning system — rpiboot is still available on Raspberry Pi Compute Module 5. Raspberry Pi Ltd recommends using a host Raspberry Pi SBC running the latest version of Raspberry Pi OS and the latest rpiboot from https://github.com/raspberrypi/usbboot. You must use the `Mass Storage Gadget’ option when running rpiboot , as the previous firmware-based option is no longer supported.
