DNA chips are produced by a company called Evolv. Here's a bit of their history -

Evolv were the first company to produce a chip for a regulated device (let's simply refer to that as Wattage). That's a pretty big advancement for vaping.
DNA boards are class leading when it comes to Temperature Control. You can hook a DNA board up to a laptop and mess around with all sorts of settings, and modify the look of the screen. There's also other tools such as device monitor.
Do you use Temp Control? If not, it might be more mod than you need. If you do, then it is the best device for TC. Even so, some of the other less expensive chips nowadays are pretty good at TC.
They are excellent devices. I have quite a few of them...
