Cylewet 6Pcs RFP30N06LE Logic Level N-Channel Power Mosfet TO-220 Power Control DIY Kit for Arduino (Pack of 6) CYT1069

If I put 30 volts in will the output side be 5 volts without attaching this to a arduino?

I just received my item. is there a picture or schematic diagram on how to assemble this kit? which way/direction does the mosfet go into ckt board?

once assembled, is there room to attach a heat sink?
