I had this issue on one of my boards which blew out my USB bus on my PC...If you were to plug it in did it effect your USB Bus or just blow the fuses?

Yes I have 3M Industrial grade + I pressure fit to the board holding the DNA in place via the use of the tactile buttons and pressure. No need for more holes than needed. I must say though the magnets are carefully placed for a pretty extreme magnetic hold.

Some I built recently. Lastly the mean LiPo test station

I LOL'ed a little... ;-)

I must have a super secret version of EScribe because under the themes tab there is a value of 5X near the Locked click 5X setting. -XEVape

I require 3 immediately and will pay up to $10 a piece.

Buy from http://www.xevape.com - I run the site and I'm reliable enough to not send you busted devices. However as far as Reliability towards Evolv, I've built about 58 DNA200's to date and had about 6 failures. However within those 6 failures all of the bad chips were dealt with via RMA and I've had Zero issues with the process. Thank you, XEVape

I just got this today. Upon uploading settings I get Error press Up to continue. With firmware 8-21 & 8-7 With firmware 7-29 Weird...does not happen with 2015-07-29.sw-update only firmware after that date.

I was attempting to program a DNA 200 Chip today and upon plugging it into my PC the PC turned off I smelled a faint burning smell and upon turning the machine back on found my USB2 Bus / Ethernet controller to be fried. I yelled like a psycho and replaced the chip with a working one then set the bad chip aside for testing, pretty pissed off about the PC btw. I have the chip here and with no battery plugged in it accepts and programs through USB, so i updated to the latest firmware. If I plug in power and ground it still working on USB. Once I plug in the 4 pin balance connector and plug in the USB it immediately fries any power source trying to charge it. This included my $500 motherboard USB Bus... I am going on vacation Saturday until after labor day. I have a plan for tomorrow though. I'm going to get a PCI-X USB 3 card and a PCI-X Ethernet Adapter from work and rig my PC to be accessible through my vacation however I want to send this board in for a check. Upon removing the ground from the 510 the pad lifted ever so slightly however that should not be causing the issue with the charging since it was happening prior to my dumb ass adding another problem into the scenario. I'm going to bring the chip to work with me because i want to ship it out and other another batch of 10. I'll get in contact with Karen tomorrow about the order but I would like for you guys to take a look at this chip and see wtf happened. If it is in fact on your end maybe we could come to terms on getting me another motherboard however that is not what im after at this point, but im very pissed off about it none the less. -XEVape

I've build around 4 1590B box's that battery will fit just fine.

Got a board back with burnt fuse. What would the mouser or digikey part be for a fuse replacement, I have already removed the blown fuse. I would like to replace the fuse myself as to not have the user wait a long duration. Update: I read the manual and it stated the fuse is manufactured by Schurter and the part number is 3413.0332.22 Mouser.com http://www.mouser.com/ProductDetail/Schurter/3413033222/?qs=%2fha2pyFadujkDmRci6X%252bAjZpKNMNNwxjncWzATFONlvFFtZLJI1Yww%3d%3d

I fit 2200mAh batteries in the hammond B boxs. Finished https://instagram.com/p/6Yp84WAWEc Basically the internals. https://instagram.com/p/545cYQgWPy

Nice.

May I ask where you got the buttons?

I'm waiting on screws. I'm building 15 of these all different colors for a local shop. https://instagram.com/p/6Q5vAKAWHa/

Hello Dogmods

Nice buttons bro

Any reason two of my builds will charge to 96% and 99% but never 100. They are 1000mAh 11.1v 3S and i set the wH to 11.1 in the software. Thank you for your time.

Your demeanor in every post I read reminds me of the way I run my business. Keep up the good work!

With out a doubt it will fit.

I think I may have finally found a justification. I've wired up about 10 of these DNA's in my pre-production Round 1 and I've noticed that every time I go and wire the positive and negative to the board it sparks on the initial connection.. Is this due to the fact that its default is constant on? If the default was the chip being off and needing to be turned "on" would the initial spark connecting the leads happen? Thank you,

i just thought it would be a nice additional feature...

Signs of an amazing company right there!

I have absolutely no concerns of users taking my approach in fact I condone it. At this point the tact switches I use have a surface area around the actual clicky push button. The hole I slide the tact switches into are VERY slightly offset to make contact with the surface area of the tact in conjunction allow the switch to be, again very slightly, held in place. The 14AWG ground wire holds the top portion of the PCB in place because of its thickness. The 510 + is looped so that when pressure is applied the PCB pad doesn't have any resistance and pull off the board. The bottom portion tact buttons UP and DOWN simply hold the bottom portion in place and the position of the charger connector holds the bottom. I then place a sized pad in between the battery and the pcb which holds the center and absorbs any press on the DNA chip. With this approach the entire construction has 0 Epoxy and 0 Glue. Enjoy

I'll leave this up to Evolv to answer definitively but I must state that once you remove buttons or do PCB work I'm assuming the warranty on the chip is void. As far as me personally I don't re-flow to remove items I re-flow for BGA issues. When working with a PCB and requiring removal of working items that are being replaced I tend to opt-out of heating other items on the board potentially causing failure. This instance I chose to do two irons and just touch all 4 points to remove the buttons. 10 boards doing just this took me 15 minutes for removal of all buttons. I then changed tips and found the exact point to snip the tact button legs so that when mounted the USB connector did not stick out. Lastly with 12 legs holding the board up I tested pressure Thank you @XEVape
