My highly unscientific analysis of the numbers is that Trump won in many rural and less populous districts, whereas Hillary won the more densely populated districts. This by itself probably isn't much of a surprise, and the less populous districts have significantly fewer votes – but there are more of them. Combine a strong Trump performance in these small districts with an underperforming Hillary in the others, along with a number of flipped districts, and it becomes clear how Trump won. (Note: how, not why.)
Check the results for Wisconsin for instance, and you'll find a lot flipped districts. In Michigan, the Detroit stronghold saw a drop of 8,6 points compared to the 2012 vote. To be fair, it looks like Wayne County (where Detroit is) according to that map isn't fully counted so this may very well change, but it's at 98.9% reporting so that'd have to be a pretty significant chunk of votes to widen that margin.
Again, this is armchair analysis so I may very well be writing bullcrap, but it looks to me that the Trump campaign where confident in keeping the red states and focused pretty hard on flipping some of the states the Democrats really didn't think they could possibly win, along with a strong push to win Florida. Those 29 electoral votes from the sunshine state really opened things up for Trump.
The WaPo map is pretty good:
