Aha .. didn't hear about the "nichrome only" thing. But to be honest this new temperature control feature doesn't really move me at all. I don't find that I have any temperature issues with my current regulated devices that would lead me to believe that this feature is something that I want or need. My interest, in any would be the overall quality of an Evolv chip.
Temp control aside, the DNA40 has some other new features as well. 1.) Reverse battery protection 2.) Buck capability 3.) Obviously 10w more output power.
I think I may do this ..

I started rebuilding with Genesis styles, and it is a sacrilege to not use mesh
