Part 1.2：Connector Interface Definition
The AN5641 module is connected to the FPGA development board through a 15Pin 1.0mm pitch FPC flexible cable, and the FPC connector on the module adopts the upper contact method. The interface is defined as follows:

Part 2: Supported FPGA Development Board

Not all ALINX FPGA development boards have reserved MIPI interfaces. Currently, only the following FPGA development boards support MIPI camera capture and display:

Part 3: Hardware Connection and Testing
The AN5641 module and the FPGA development board are connected through the FPC flexible flat cable. We have provided a 15PIN heterogeneous flexible flat cable. Because the FPC socket of the module is in upper contact, when inserting the FPC flexible cable, the exposed metal side of the cable needs to be facing up, and fasten it as shown in the figure below:

Then connect the other end to the FPGA development board. The picture below shows the connection of the AX7Z020 development board:

The following picture is the picture connected with AX7Z035 or AX7Z100 FPGA development board:

Download the test routines in the VIVADO software development environment to the FPGA development board. We can display the binocular video image to the HDMI display through the HDMI output interface of the FPGA development board. The video display effect is as follows:
