I can totally see that giz_60 !

Now my biggest concern is how to get the board out since the wires are on the other sides !
I' no expert ! Like i said ealier i think i have to unscrew (if i find the right tool) the 3 torx screws at gnd and then check the wiring !

Thanks

hey, so i took the board off... and it looks like this IMG_2811.JPG 

it appears the #6 has nowhere to connect to...
Can someone tell me why there's only one wire on this side ?
the black wire is connected on #5 (up +) ? Is it normal there's no wire on #4 (down +) ?

Somebody help !!!! what's wrong with this setup ?

Thanks !

Sure doesn't look like a 75 board...check the difference from this picture off of Evolv's website...

dna75.jpg 


Button layout is completely different, as well as components on the board....markings on the board, etc...you may have a cloned board. But it appears that the black wire has been added & connected to pin #5 is probably why the down button is also activating 'up' as well. You might try removing the black wire & see if that fixes your issue.

I think the Dna board is underneath the one you see, cause there a 2 boards on my set up

I can see the "up" written on one side and "down" on the other side just like it shows on the dna picture.

Also, when i connect to evolv  website via escribe, I have no issue, I don't think it's a clone issue...just a wiring one.

cutting the black wire ? are you sure ????

thanks  !!!!!!

I didn't see the second board in your picture till I blew it up...if the #5 pin on that board is connected to the #5 pin on the DNA 75 board, then the down button on that board is connected to the 'up' circuit on the 75 board. Judging by your picture, that wire appears to have been added on...Remove it at your own risk, but that's what I would try.

i'm a little sceptical on cutting the wire...no offense !

i'll wait and see if someone opens up its VapeDroid to see what the wiring should be !!!

thanks !

No offense taken...you should be able to tell if the wire has been added by the solder joints. Also, there are no other wires coming from the other switch either. It's possible that there was some kind of issue & someone added the wire to get the down button working & soldered it to the wrong pin...at this point, it is a guessing game, since you got the device second hand...Good Luck!!

I'm guessing here but all the +'s are really the same no matter their label. So if you pick up power off just one it could power the added board for all buttons. 
How about a picture from the side showing how the 6 connections are made from one board to the other?

the up and down button's neg pin-outs on the dna are tied directly together / to ground. looks like VD used a common ground path for both -/+, requiring the use of only 3 of the 4 available -/+ pin-outs. this is common practice to save material (wire) and time.
  
short answer - the last up button pin-out not being soldered is OK and not needed. 

@flo_46 can you take a better, closer pic of VD's daughter board for me? i might be able to help you out.....


also... can you check for continuity between these two point of the switch. should have continuity when button is pressed, no continuity when not pressed.

Hey,

so I took off the black wire (even if I shouldn't have!!!) and the change is that the left button is inactive now ! the button on the right hand side still works properly.. here are more detailed pictures;

Any thoughts ?

Well, that at least that verifies that the wire was the cause of the down/left button to act like it did. It would appear, now this is pure speculation based on info available, that there was an issue in the past of the down/left button not working, so someone tried to remedy the issue by adding the wire to connect the switch direct instead of through the board circuitry, and soldered it to the wrong pin. If you have a meter, you check continuity between the switch...where the wire was soldered to...and the #4 pin.

I guess you're right ! it really isn't my area of expertise...

If I could see how a "functionning" C1D2 Vapedroid is wired inside I might solve this issue !

Thanks for the update thought, I'll try and contact VapeDroid for more info.

if you want to try something, solder that wire back where it was on the leg of the down button (make sure it's soldered on the SAME leg where it originally was!) and solder it to the 3rd pinout (circled in red). it was originally soldered in the wrong pinout .
THIS FIX WILL ONLY WORK ASSUMING THE ACTUAL BUTTON WORKS (which i'm guessing it does since it functioned as a second up button because of the incorrect placement)!

r wait and see what VD says. up to you. if i had the board in-hand i'd be able to fix it for you in 10-15 min. if the button is bad i have replacement SMD tact switches of that exact model. i mainly buy them for replacing vaporshark's faulty firing buttons.
