Is there PCI Express in Skull Canyon? When I wanted to choose a mini computer and the question was whether I can use PCI Express so if it is busy with the WI-FI module, then you can show it where it is on the photo.
The KY NUC has two x4 mini-PCIe (M.2) ports. In your picture, you have SSD installed in one of these ports. The second is to the right of the one that is currently occupied. The wireless card is permanently affixed to the board and utilizes a totally separate x1 PCIe port.
Hope this explains it,
