Screw Size for Mounting Holes on NanoPi M2

[Finno]

Hi Folks,

I was wanting to confirm the screw size needed for mounting standoffs on the M2 board. It looks like m3 size screws to me but can't find that confirmed in any of the docs. Or did I miss it somewhere?

Thanks.

I found some 3mm standoffs and tested so I'm pretty sure it's m3.
