There's also no "I'm ambivalent about these features" option. "I do not like it, Sam-I-Am" becomes the default option, since the others are super positive about the product.

From my chair, none of the features of the SD540 stand above my primary criteria for selection of a speed-controller, which is "Reliable, as verified by real FRC teams using real hardware on a real robot".

Not to imply that the product isn't reliable, just that being burned to the tune of a set of speed controllers during build/competition season is enough disincentive to keep me preferring more tried-and-true offerings.

I like the idea that the output has a higher signal frequency. Plus if it is more efficient at transferring power, it won't get as hot. Time will tell if these differences are significant.

Big plus in either case is now we have smaller, lighter and more chip resistant motor controllers! This is a big change from just a few years ago.

I haven't seen anything that states whether or not it is FRC legal for 2016. If it isn't, then why are we wasting time on it?

So yeah, it's legal.
