R2 Mini Pci-E Question

Banana Pi Router design
1

Hello all, a very simple question that I hope you can help me with. I have thoroughly confused myself.

I have a Banana Pi R2 which has a Mini PCI-e port. (52 pins I think) I want to use a card that is PCI-E 2.0 which has 32 pins

Are these compatible, is there an adapter available?

I think you need such kind of adaptors to use your PCIE card, thanks.
