Hi @"lincolnxlw"#p9183 , It really depends on the sensor/resolution. Eg IMX378 doesn't require 4-lane MIPI connection even for higher resolution (4k/12MP), while others, like IMX582, do.

Can I use two 4-lane MIPI camera modules with DM1090FFC (OAK-FFC-3P)

According to the documentation for DM1090FFC

The OAK-FFC-3P (DM1090FFC) baseboard has 3 FFC interfaces which allows for:

Two 2-lane MIPI camera modules, eg. OAK-FFC-OV9282 (stereo pair)

One 4-lane MIPI camera modules, eg. OAK-FFC-IMX378 RGB camera module, or additional OAK-FFC-OV9282 if RGB camera module is not required

However, when I connect two 4-lane MIPI cameras to right and left sockets (both as ColorCamera) and leave the RGB socket open, I am still able to run things like Mobilenet inference, Yolo inference, h265 encoding for both cameras. The 4-lane MIPI cameras I tested and are proved working are IMX378 modules, IMX214 modules and IMX477 modules.

Is this a reliable behavior from DM1090FFC? If I just need to run two 4-lane MIPI camera as ColorCamera, can I use DM1090FFC for that?

Hi erik

Thanks for sharing the documentation! I was only reading the one for the camera module and didn't realize there is also one for the sensor.

Thanks!
