2.1 Attaching the Compute Module 4

1. Carefully align your Raspberry Pi Compute Module 4 (CM4) with the CM4 socket on the CM4-IO-BASE-B board. Ensure the connectors are correctly oriented.
2. Gently press the CM4 into the socket until it is securely seated. Do not force it.
3. If using a metal case, install the CM4 and IO board into the case following the case manufacturer's instructions.

2.2 Connecting the USB HDMI Adapter

1. Locate the FFC (Flat Flexible Cable) connectors on both the CM4-IO-BASE-B board and the USB HDMI Adapter.
2. Gently open the latches on the FFC connectors.
3. Insert the FFC cables into the corresponding connectors, ensuring they are fully seated and correctly oriented.
4. Close the latches to secure the FFC cables.

2.3 Initial Power-Up and OS Installation

1. Connect a 5V/2.5A power supply to the USB-C power input port on the CM4-IO-BASE-B.
2. Connect a display to one of the HDMI ports (either directly on the CM4-IO-BASE-B or via the USB HDMI Adapter).
3. Connect a USB keyboard and mouse to the USB 2.0 ports.
4. If your CM4 is a Lite variant (without eMMC), insert a microSD card with a pre-installed Raspberry Pi OS image into the microSD card slot.
5. Set the BOOT selection switch to the appropriate position (ON for USB-C boot/programming, OFF for eMMC/microSD boot).
6. Power on the device. Follow the standard Raspberry Pi OS setup procedures.
