Arducam Multi Camera Board V2.2 pin assignment

Hi, I would like to combine the Multi Camera Board with another extension board. However, this other board uses a GPIO pin that is already in use by the multi camera adapter board. I am going to solve this by using jumper cables to change the pin assignment of the board. Besides the 3 GPIO pins that are used for camera selection, which other pins are necessary to operate the multi camera adapter board? Thanks in advance.

I didn’t get a reply to my thread about the doubleplexer either

Dear timothy,
About the pinout of multi-adapter-board, we use the folliwing pin source shown as the below image.
