Quick Start Guide for Multi-Camera Adapter Board

Hardware

Abstract

Arducam offers multi-camera adapters to accommodate up to 4 camera modules on a single Raspberry Pi and switch between them quickly. The HAT-style quadruple adapter fits well with the Raspberry Pi A&B series, and the double adapter is perfect for the Pi Zero. You will read more about it in the following chapters.

  • Hardware Structure(Example as B012201)
  • Connect and Insert the Multi-Camera Adapter Board into Raspberry Pi
  • Connect the cameras to Multi-Camera Adapter Board

Software

Warning

We currently only guarantee that the Camera Adaptation is supported on Raspberry Pi Bullseye systems

Update Kernel Version

Note: Please make sure your kernel version is up to date (at least 5.15.63 or later)

m1

How to update the Kernel bersion:

Modify the Config.txt

For Quad-Camera Adapter Board(B012001):

sudo nano /boot/config.txt

#add Following content: 
dtoverlay=camera-mux-4port,cam0-<camera sensor name>,cam1-<camera sensor name>,cam2-<camera sensor name>,cam3-<camera sensor name>

#Find the line "camera_auto_detect=1" and modify it: 
camera_auto_detect=0

Note

Please manually add the number of cam according to the number of cameras you have connected.
Example: if you have three IMX219 cameras connected, enter:
dtoverlay=camera-mux-4port,cam0-imx219,cam1-imx219,cam2-imx219

For Dual-Camera Adapter Board(B016601):

sudo nano /boot/config.txt

add: 
dtoverlay=camera-mux-2port,cam0-<you camera sensor>,cam1-<you camera sensor>

Note

Please manually add the number of cam according to the number of cameras you have connected.
Example: if you only have one IMX219 cameras connected, enter:
dtoverlay=camera-mux-2port,cam0-imx219

Run the Multi-Camera

Use libcamera apps to access the Multi-Camera

libcamera-still -t 0 --camera <choose camera num>

Example:

m6

Attention

For another libcamera apps like libcamera-raw, libcamera-vide, etc. You will need to manually add --camera <choose camera num> behind the command
