====Connecting the module====
SBC computers feature two types of camera connectors:
*FPC/FFC 15-pin/1 mm, e.g., RPi3, RPi4, Jetson Nano
*FPC/FFC 22-pin/0.5 mm, e.g., RPi5, RPi Zero 2 W, Jetson Orin
The '''KAmod IMX477''' kit includes ribbon cables compatible with both standards. When connecting, make sure that the metallic contacts of the ribbon cable are facing towards the connector contacts on both the '''KAmod IMX477''' module and the computer board.

The correct orientation of contacts is shown in the figures.

====Running the module on Raspberry Pi OS====
Connect the '''KAmod IMX477''' camera module to the <code>CAM/DISP0</code> or <code>CAM/DISP1</code> connector according to the previous instructions.

The new Raspberry Pi OS (Bookworm/Trixie) has built-in support for the IMX477 sensor, so no additional drivers are required. After booting Raspberry Pi 5, you only need to edit the <code>config.txt</code> file. First, enter the following command:

<div style="background: #f8f9fa; border: 1px solid #a2a9b1; padding: 10px; border-radius: 4px; width: 1100px">
<syntaxhighlight lang="sh">
sudo nano /boot/firmware/config.txt
</syntaxhighlight>
</div>

Now locate the following line in the file: <code>camera_auto_detect=1</code>

and change its value to 0: <code>camera_auto_detect=0</code>

Next, at the end of the file in the [all] section, add:

<code>dtoverlay=imx477,cam0</code>

or

<code>dtoverlay=imx477,cam1</code>

depending on which connector the camera module is connected to. If two camera modules are connected, add both lines.

Finally, save the file using the key combination CTRL + O (confirm with Enter) and exit the editor using CTRL + X (confirm with Enter). After rebooting with the command <code>sudo reboot</code>, the single-board computer is ready for use.

You can start the camera preview using the command:

<code>rpicam-hello -t 0 --camera 0</code>

or

<code>rpicam-hello -t 0 --camera 1</code>

depending on which connector the module is connected to. To stop the process, press CTRL + C.
