This wasn't in the vid. It's on the Protovapor Blog. Something they are experimenting on.
The DNA-40 brings in a new era of "temperature controlled vaping" - and the use of NR wires (Nickel) for heating the coil to maintain the temperature around selected ºF (soon switchable with ºC as well).
Off course the board is also capable of being used in its regular DNA mode with a 40W max. But the key feature is the introduction of TCV.
Other features include:
1. Reverse polarity protection
2. Adjustable from 1W to 40W
3. Fires until 0.16Ω when Kanthal / Nichrome wire is used
4. Fires until 0.10Ω when NR wire is being used
5. Automatic sensing between type of coil used (NR or R wire)
6. Max Temp adjustable till 600 ºF
7. Removable 'rails' used for mounting the board
8. Voltage step down ability
9. Dim time reduced
10. Other standard features of the DNA boards still continue
