Hello,
I am not able to access the link for the T25N01A connector that you pointed out in response no.4.
As mentioned in Question 11, of the following KBA: CX3 Hardware: Frequently Asked Questions - KBA91295
You can interface your custom daughter card to CX3 RDK by using a interconnect board to interface with the CX3 connector to the image sensor connector (T25N01A).
You can also refer to this link to download to the schematics of the CX3 Denebola RDK where you could get the connector of the main-board and you can acquire a suitable female connector for your daughter-board.
Also, you may need to acquire the female connector for the image sensor connector (T25N01A) and route the lines accordingly to be able to interface them.
Or you can go ahead and build a custom board with CX3 and the image sensor (no need to acquire the CX3 board connectors) and please refer to Question 8 of the above-mentioned document for guidelines.
Regards,
Yashwant
