Looks like you have a battery connection problem on the mod

This is a known problem that has been previously reported, Happened to me, and I RMA'd the board and 2S is perfect for me and powerful enough for most

I'd imagine they're a bit busy at the moment, DNA60 time

I'm wondering why anybody still uses NI200 wire, it's a not ready for prime time coil material, , too unreliable, I haven't used it for a couple of yrears

I think it's time for the 250 to have its own category, these differences would be so much better enunciated

BTW, is that noted anywhere in the docs and I missed it?

Ahhhhhhhhh, so I'm not crazy Thanks dw

Just got the DNA250, and like all DNAs, first thing I do is put the screen on (no batteries), plug it into the USB, and test display and eScribe connection. The board connects to eScribe fine, but no display. I have a few DNA200s so I swapped the screens, and it works in the 200, but not the 250. I can change the power up and down and it registers on the device monitor, so I think the board is fine Is the DNA250 different then the 75, 200 and 60, requiring batteries to power the screen or do I have a defective board?

Nick, we have much work to be done to get mods ready for the new chip, Can you please publish the USB board CAD, Thanks

That's great James, glad to hear,

All I can say is bout time Evolv /topic/68206-topic/?do=findComment&comment=913381

Make very sure there isn't a single strand of wire from one connector port touching the other wire or port

Aren't those leads Nichrome 80, not NI200?

The fact the fuse blew in the first place is a problem, it wouldn't be up to Evolv to fix the device, just replace the fuse on the board, so you're back to the original problem. To me, it sounds like you have a wiring problem, happened to me, so I re-wired everything but the 510

Are you saying you sent it to Evolv to repair a blown fuse,and this is how they returned back to you? What caused the blown fuse?
