Ok. Not an expert but shall i try.
Got FU024 Mofset on my Arduino Nano(clone I believe) and have decided to replace it, but, there's a problematic situation, is this mofset been installed by manufacturer to get cost down, or, is this a quality mofset. Hard to tell. If it's quality made, I'll replace it by the same(and put heatsink on it), but if it's been put in so it works "just on edge" why shouldn't i try put different in?! Better?!
Got an idea to replace it with Logic Level mofset RFP12N10L as it opens fully and closes fully when needed, but it's turn on voltage starts at 2 with max 4v compare to FU24N which opens at 1 and turns off at 2v.
Been told by one smart guy that i will be unable to install Logic Level without modification.
