I'm not sure which I find more interesting about that pic... that it's showing basically the same problem with the same chip, or that the board in the DNA20 FT clone is so different from the Cloupor DNA30 clone. The Cloupor appears to be very near to a 1:1 clone, but the FT chip is quite different from the real DNA20.
And what is with the removing of the part numbers from the chips on the clones? Are they trying to hide the fact that these are the same chips used on the real DNA30, or are they just trying to make it look like a real DNA30 which also has the part numbers removed (usually)?
Yea, that was my FT Hana DNA20 clone that burned. I'm relatively sure I know what happened on mine. I assumed it was the hot glue covering the chip leading to an overheat condition, but after thinking about it I remembered that I had seen several "Check Atomizer" messages earlier in the day. Loosening and retightening the tank resolved it, so I kept on vaping. In the end, I think my Aerotank Mega was shorting out with the overly large 510 pin in the FT clone. The short protection caught it several times, but apparently one snuck through and fried the chip with a dead short. It was obvious when it happened ... I hit the button, didn't get any vapor, and immediately smelled burned electronics.
Looking at the connector on my Aerotank, I'm surprised it worked at all. The center connector doesn't protrude hardly any at all from the bottom of the 510. Its pretty obvious that in order to get the Aerotank pin to make contact with the 510 pin on the clone, the sides of the connector on the Aerotank are going to be dangerously close to shorting out. The center pin in the clone (at least the one I had) is simply too large. I compared it to every other device I have here, and none of them have a center pin that is this wide.
I ordered a Cloupor clone, and it should be here tomorrow or Thursday. I'm sending the DNA20 clone back to FT for a refund. I plan on examining the Cloupor when it arrives, and if it suffers from the same wide center pin issue, I'll either replace the entire 510 connector, or pop that pin out and see if I can file it down.
I was going to put an Evolv board in the FT clone, but decided against it. I ordered the Evolv DNA30 board last week, so I'll either keep it for a spare for the Cloupor clone, or build another dna mod on my own.
