Release original Eagle files

[alexwhittemore]

I appreciate that you're going the open hardware route, and thanks for the schematic PNG! Although the really USEFUL information is the layout, and specifically hole size (for the BNC holes) and signal arrangement (for interfacing with the data logging/OLED board).

Specifically, I'd like to spin a version of the board that included a full-sized USB B connector. The mini-b connector is probably the worst choice - 1A and it's a very poor connector in general, wearing out much quicker than the micro-b connector (which supports 1.8A on the power pins). But since many tablets and so on now support drawing >2A, and since the OLED backpack supports even beyond 3A out of the box, standard USB micro-b is even non-ideal. My plan is to make a USB3.0 version of this board with a full sized input and output jack, but of course, the proper layout would be helpful :)

Hi,

I do plan on releasing the files. The PNG was just to get something out
there till I am ready to release the files. I need to figure licensing
among other things. It will be open source but I want to pick the one that
best fits.

I could make a USB micro version once I move away from hand soldering.
Which is the reason I went with mini. The pins stick out just a tad more
than micro which make it easier to solder. I will be able to use a reflow
oven soon so I can switch over in a later version or separate product line.

If you give me some time I should be able to release the design files soon.
I like your improvements to the design. Maybe we can work something out and
create as another product version.

Ahh, I hadn't considered the hand-soldering question. Since USB3.0 is rated 1.8A, so too are all the connectors regardless of size, however given the much larger pins in the full sized A and B connectors, I can only imagine they will perform better than the smaller cables. They're also totally backwards-compatible with 2.0 cables, so there's that.

I'll need to do some current handling testing, but the plugs themselves are DigiKey P/Ns GSB311131HR-ND and GSB321131HR-ND

I think I am going to prototype a micro USB version on my next prototype run. I should be getting a reflow oven soon anyway. But I would like to try hand soldering it as well. I am getting good at the small stuff.

I feel like I've seen discussions on eevblog and/or DP's forums about micro
connectors that were easier than others to hand solder, but thinking about
it, it's more likely those were mini USB.

You could always try the hot-air setting of a pencil torch

(assuming you don't have a hot air station, that is)

Hmm, well I do have a hot air gun, but it only has two temp settings. Its great for de-soldering though.

If it melts solder, it melts solder :)

LOL ;)

Hi,

By any chance, have you tried the Java app? I wanted to get some feed back
on the layout with different resolutions. I am thinking I need to make the
app wider instead of longer. I also just committed the app for different
version of java and x64 library which was needed for OSX.

Thanks

Not having the backpack, I haven't thought that far ahead :). But I can take a look!
