Socket-wise yes, but you'll have to either check for a pre-applied bios update or do it yourself to make the jump from skylake to kaby lake support.

Edit: Bios F20 or newer.

What do you suggest with it to get a buget board or what ?

Really depends on your location, since pricing and availablity can vary widely.
With the assumption you're located in the US.
