Intel NUC M.2 expansion capabilities

Hi,

I bought an Intel NUC5I3RYH and I need some more details on the M.2 connector: normally it is used to host an SSD, but in my case I was wondering if I could use the standard SATA port for the hard disk and, instead, the M.2 connector to host a M.2 capture card to acquire an HDMI input. On the technical datasheet it is reported "Expansion Capabilities: One M.2 connector supporting M.2 2242, M.2 2260, and M.2 2280 (key type M) modules" but no more information are provided.

Is there something in particular I have to do to make this work?

Any suggest will be particularly appreciated.

Thank you very much,

Sandro
