Dear OAK FFC Hardware Experts, We would like to sync the RGB image of OAK FFC IMX477 M12 with the stereo pair (i.e. connect FSIN on the FFC cable to the XVS signal of the OAK FFC IMX477 M12 module). But we could not find any label of the following testpads/testpoints : ![IMG_0455](https://files.slack.com/files-pri/TCBK1BGU9-F05R6JRRS3E/img_0455.jpg) [upl-image-preview url=https://discuss.luxonis.com/assets/files/2023-09-06/1693982227-108950-image.png] Could you instruct or do you have the PCB layout to share, please ?

Hi @"l4es"#p11761 , Here's signal info for the 4 pins: [upl-image-preview url=https://discuss.luxonis.com/assets/files/2023-09-07/1694083745-307168-image.png]

@"l4es"#p11761 Only the adapter is discontinued, as it's not needed anymore - it was needed with the[ OAK-FFC-3P-OG](https://docs.luxonis.com/projects/hardware/en/latest/pages/BW1098FFC/). [upl-image-preview url=https://discuss.luxonis.com/assets/files/2023-09-07/1694083823-642801-image.png]

Hi @"l4es"#p11776 , We haven't tried it yet, but I assume it should work.

Sync signal of OAK FFC IMX477 M12 ?

Meanwhile, the module seems to be discontinued by Arducam : https://www.arducam.com/product/arducam-12mp-imx477-mini-high-quality-camera-with-m12-mount-lens-and-adapter-board-for-depthai/

Hi erik ,

Thanks very for your answer and confirmation. By the way, for the sync/alignment of RGB and depth, what would happen if we configure the snapshot mode for AR0234 pair and the continuous mode for IMX477 as their only supported mode, please ?

Thanks and best regards,

Khang

Hi erik ,

We haven't tried it yet

Did you mean that the RGB and stereo pair in OAK-D cameras were not hardware/frame-synced ?

Best Regards,

Hi l4es ,
Stereo pair is HW synced, and IMX378/IMX214 (sensors that we use in our finished products) are then software-synced, as depthai does some line-skipping every so often (on the rolling shutter color sensor) to achieve sub-ms accuracy.
