I am making a boost converter following this Tutorial but I don't have the exact MOSFET. I have 2 motherboards laying around and they have some MOSFETs on them some of the names are: P3055, K3918,6670AL(datasheet inserted). There are high switching speeds but the datasheets don't have the max Freq. I am using an Arduino nano btw. Please give me advice on which one I should use. I also have MOSFETs from an old RC car's h-bridge but was not able to find a datasheet
