About PCIe Daughter Cards for Agilex™ 3 FPGA and SoC C‑Series Development Kit

Dear Support Team,

I would like to ask for clarification regarding the PCIe add‑in cards for the Agilex™ 3 FPGA and SoC C‑Series Development Kit.
In the User Guide, Table 5. Available PCIe Daughter Cards lists the following two models:

3.3. Modes of Operations • Agilex™ 3 FPGA and SoC C-Series Development Kit User Guide • Altera Documentation and Resources Center


・DC-A3PCIE
・DC-A3SOCPCIE

Could you please provide documentation that explains the differences between these two daughter cards—such as their appearance, functionality, or any other technical distinctions?

I have already downloaded the installer package for the development kit,
but the documents folder was empty, and I could not find detailed information about these PCIe daughter cards.

If there is a specific document, datasheet, or application note that describes these two cards in more detail, I would appreciate it if you could point me to the correct resource.

Thank you very much for your support.
Best regards,
Gesso
