Spector - Thanks so much! I think I figured it out and you are 100% right! I was expecting to get a connection without power going to the board, just as you would with the stock USB. So I connected the ground and a battery and I’m good to go!! Finally! Thanks for your input.

@greenj22 Are you going to leave that permanently soldered? I notice a BB on your bench, and my connections are always removable cuz I just couldn't figure how to mount the board
Hi Wayneo,
I have sorted out USB install in BB’s, but it is a fair amount of modding. I just wanted to try using different USB or taps that I could install with less modifications.

Hi All,
I have looked at, read, re-read, and been attempting to get EScribe/data connection using a generic USB breakout board.
My understanding:
From breakout board to DNA60:
VCC to pin 15 via 10K ohm resistor
Data + to pin 14
Data - to pin 13
@ChunkyButt200 can you please help?
No connection. I’ve tried this several times on/off for a looooong time.
Help is very-much appreciated in advance.
And yes, USB cable is data capable.

Yes - all you need to do is pin 1 (Down +) and pin 6 (up +) then the third wire is simply a ground and can be connected to any other ground/bat - pin (such as 2, 4, or 5).
Cheers!

Hi all,
I just received small screen 60's and the display is garbled. I'm guessing it's something simple - like I just need to upload a specific display size or something via escribe.....but not quite sure. Anyone?

I see it differently. It would and should cost LESS. Do you really think that they are not able to make the 250 capable of running off of a single cell? They could pass along the savings of not even messing around with producing a DNA75 (I bet they could save some money if they dropped the LED. Lol) to the consumer or simply make more money - the latter is what I'm thinking is the hold up. And with mass production, the cost of those components only decreases I'm pretty sure. The 75 is marketed as a cheaper alternative, but is it physically $40 cheaper? I bet not. I'm going conspiracy theory here and saying that I think it's all for the revenue. The more products they can offer the more money they can make. There are many analogies for this. Why have multiple boards that likely cost VERY close to the same to manufacture when you could simply sell one? I understand they are different boards, but given the fact that the 250 can run any configuration EXCEPT 1s is very suspicious and odd to me.....unless I'm worng and they offer the firmware for it. Hell - they just came out with the 75C and added a larger screen, Escribe, and 9 volts yet the board is the exact same size. Sure, components cost a bit more, but my point is that they likely have the tech/talent in house to, for example, make the balance tap a breakout component! Why not?! Then you have a board w/ an identical footprint to the 75. Just an example. Make one board for 0-250 watts of that footprint - simple.
I love this company - FYI. I just was sitting here and had that thought. -
Hey all,
I was thinking just now; why doesn't Evolv simply make ONE board capable of running on a single cell or a 2S/3S configuration? I'm not an electrical engineer, but obviously the DNA 250 can run at 75 watts, at 166/167 watts, 200, and 250. These boards are all the same footprint essentially (the balance tap being the notable difference) so basically any mod that incorporates a DNA 75 "frame"/layout, could fit a 250 (minus the 75C's b/c of the screen)...which leads me to wonder why....why 2-3 different boards? With all of the R&D/tech built into these chips, I can't imagine it being difficult or costly to simply produce one board capable of running on a single cell or multiple cells. Almost like a 250 can be run at 167....why not have Escribe firmware to allow that board to run a single cell at 75 watts?
This now leads me to my final thought, which I would rather be completely wrong about: Do the 75, 200, 250 boards all exist simply as a way to sell more boards? Is this to have a larger catalog of products? Why sell three different boards when one board could do it all? I would also think this could cut manufacturing costs, and streamline mass production, marketing, and the sales cycle - all allowing a higher gross profit.
What makes more sense - genuinely? I know the 75 is marketed as a more affordable chip, but would they not be able to play with the sale price of one board capable of it all? I can't see the justification of charging more for one board that can run all cell configurations. I think the 200/250 price point is the ceiling, but that's just me. Is it more cost-effective and better for the consumer to produce and sell 2-3 boards....or who's best interest is it in?
EDIT: I suppose the balance tap adds in, what, about 4 mm? That is a nice little size difference to have with a DNA 75 vs a 250....but still! -
I know people have soldered new small screens to their small screen boards, but has anyone ever tried or looked into soldering a small screen to a large screen board, such as the current stock of DNA 60's?

i soldered very thin enamel coated copper wire directly to the usb data+ and data- pinouts. the 2 amp charging, QI wireless charging, reverse battery buzzer, etc. all work.
That is pretty brilliant! Really nice work!!! -
How did you get EScribe to work through the daughter board? Are you using the VS USB and getting the 2 amp charging?
-
I have a Lavabox M and have been having similar problems. It's the battery contacts. They don't hold as tight after time. It sounds obvious, but just try and move around the battery as you have a battery inserted until you (hopefully) have full contact. After that, (AT YOUR OWN RISK) a small piece of copper/brass slid between the negative terminal and the battery should work as a temporary fix. Just make sure it's not too big, but the inside of the lavabox battery bay is all plastic anyway.

I agree completely Lipos are the way. Period. I don't understand the desire to swap 18650's when you can do the same with a lipo pack, let alone the power to size difference. One thing though; "grafine" or graphene battery technology is not anywhere close to being available to the consumer market. It's a pretty crazy technology that's still being researched. Turnighy "graphene" batteries, I have found, are the most superior lipo packs available to consumers. They may be a bit thicker due to their high (65C) ratings, but worth every penny and a small reduction in total mah IMO.black lace said:I think the 18650 batteries are inferior and the space would always be better used up with lipos, some argue that the 18650's are quick to change out and use them for that reason,,, in my mind its allways going to be swings and rounderbouts, the larger capacity you go on a lipo the bigger it will get so the bigger the mod, have you looked at the grafine equivelent batteries, you could upgrade yours with one of thoes..

Agreed, 110%. Evolv's customer service is second to none. I can't tell you how many boards they have helped out with, including direct phone calls from Nick w/ Evolv. As others have posted; show us the build. Retird has helped many people here by zooming in on those photos and literally diagnosing problems on the fly. Dont give up on Evolv, or your mod. They are a great company in the US doing amazing work for us vapers. One last thing; I was having a good deal of trouble with boards, and ultimately trashed (in a bag I kept) many boards. I have since refined my soldering and build skills and resurrected boards that had actually went "poof" with a bit of smoke! Evolv's products are damn close to as bulletproof as possible.retird said:@jamtwo, I've seen, many times, where Evolv has replaced boards that were damaged by the end user during installation, or even out of warranty, even though it was not covered by the warranty. I understand your frustration but can't agree with your evaluation of Evolv as a company and their product(s).
Can you post pictures of your build showing only the board (front and back) and the wiring as we may be able to do a bit of long distance visual troubleshooting and possibly assist you. I do see cold solder joints and a missing ground pad in your post 1 picture. A picture of the battery and the attached connector (s) would be helpful also.
Lots of folks here that really try to help .......

Also, as an update after running 60's for a few months - they are fantastic little chips. Truly amazing. Perfect balance of functionality/technology and form factor.retird said:
It's normal that the 60, 75,200, 250 vapes differently from the DNA40. I noticed it in TP mode and one reason is the preheat feature of the newer boards. Just adjust the 60 to your liking and enjoy.... I kinda relate it this way: My 2010 vehicle and my 2016 vehicle are the same manufacturer and have same similar equipment but drive differently and gas mileage is different....
EDIT: A very well known "modder" spent some time comparing the DNA40 vape to the 200. She came up with a setting on the 200 that closely mimics the 40. Here is what she came up with:For a DNA40 vape:Set Preheat at 45WSet Punch at 5 -
All of the screens are compatible from my experiences. Even the ones that state otherwise.

Yeah. I'm not sure, based off the data sheet and in general. Part of me wants to just think b/c I have the 60 USB, I could just run the 11/12 lines from the board to USB to 60 USB in parallel, then wire the 13-15 straight to the 60 USB, as those are the data lines.....= 2 amps? (Hopefully)
-
Thx for the reply! I am using the DNA 60 Charging board....but I think you're talking about the adding of a TP4056 or an Evolv standard 1-amp USB? So is what I was thinking correct, but add in the resistor?

DNA75 "Billet Box"...aka an AI-1 75

Hi there!
So I had a few 60's laying around and got restless and threw one in a SS Hana temporarily. It's a truly great little chip.
I have been trying to sort out how to integrate 2 amp charging with it. Would one just run off the pin outs 11/12 (splice/add) additional lines over to another USB, then go from that USB to the Satellite USB? A TP4056, for example; Would you go from 11/12 to the TP4056 Battery +/-, then from the in/out of the TP4056 into the Evolv USB Battery +/-, along with the Data Lines striaght from the 60?Thanks in advance! -
Or:

If helpful, the USB Satellite Board is the exact same width as the chip (DNA 40 with rails cutoff/DNA 30). Other than that it is essentially the same depth.

That's a good analogy. It's true - I'll likely be able to go in and tune the board a bit more and am just expecting it to plug/play and vape like it's predecessor. It's a great chip though, no doubting that. I'll give it a shot. -
turbocad6 said:
I considered the same but once you take into account that the usb module really doesn't take that much more space than a connector it's just easier to mount the usb and be done with it if at all possible
Yeah - true. The only exception would be when you are able to just "tuck" the tap inside the mod....that way you can have more flexibility where you run the 5 lines and also if you can't route the lines where you would like or fit a USB where you would like. Under those circumstances, it would be better than having the USB inside the mod (no external port/access), for shorts, etc. Again - a solution for very unique circumstances. Maybe it could also work for people whom want to retrofit a VS with 2 amp charging. They could just run the two lines for +/- to the VS charge board and then have a tap inside. That way they could have the 2 amp charging still, not have to mess with the VS USB, and still have access to Escribe. Yet again - another option for some under special circumstances. Otherwise, mounting the Satellite USB is optimal of course.
On a side note, I wonder if you could just take a separate Evolv 1 amp USB or TP4056 and wire it in parallel with the Evolv Satellite USB for 2 amps...? Sounds doable.....I think... -
retird said:
How about a screenshot in Device Monitor while firing the 60..... showing relevant data on the graph..... thx
Here you go. All seems to look ok to me in DM, but maybe I'm missing something......The 60 just doesn't vape the same under replicated function with a DNA 40. Idk....
Graphene LiPo batteries are on the market. Anyone know anything about them?

True graphene batteries don’t exist. These are just a fancy wrapped, higher quality, LiPo. They are great cells, but they are also substantially bigger relative to a battery of same mah. They have insane C ratings, but we would never need the amps they are capable of. Less internal resistance and voltage sag, but that’s to be expected w/ any lipo.
IMO, a 1s (3.7v) lipo with 2-3 amp charging and a DNA60 is the way to go.
