Have you measured the actual power consumption of the the [color=rgb(40,40,40);font-family:helvetica, arial, sans-serif;]CC3000EM while it's fully running?[/color]

Sure, you'll all be able to have you're saying about it and yes, I can put the Eagle files on CodePlex or elsewhere later on. Just so that you know though, in couple of days I'll be going away for a week and I'm pretty sure the design won't be ready until after I get back.

BTW, the monster dac is still playing just fine ... although now controlled by jremote from an ipad via an pc/usb. Like to have that changed into some embedded solution ... but with those rates .... do not know if that will work ... time will tell ....
Ah yes, any new pictures of that monster of yours?
The driver for my wifi module is far from complete, it can scan for nearby wlans, connect over dhcp and ping other hosts on the network. I'm currently working on the UART variant but will switch to the SPI version (PCB supports both) when I get the hang of it.

Ah, over air firmware updates - cool!

What, are you leaving this world for another planet so soon? ;-)thx 4 the fish.
#51200 Spark Core (TI CC3000) Porting for Super WiFI Mini?
Posted by hanzibal on 08 July 2013 - 09:06 AM in Netduino Mini
Don't worry, I won't use anything smaller than 0805 or I can't solder by hand. I suppose the CC3000 will require re-flow but even so, placing will be done manually.

That is some great work there!
I saw your other post about LEDs and there will be plenty of time to change the design before manufacture.

Sorry to hear that, have you tried the Texas E2E community?
They are very helpful and you usually get help directly from TI employees working within the very field in question. At one point they even called me on the phone and that without me having pretended to be a big shot with 1k+ units planned for production

A $20 wifi board is great value, especially for a single unit!

It's much smaller than it looks but it's abviously designed as an add-on for some TI general eval platform. You only need to connect SPI bus, power, gnd and the enable pin so it's quite simple.hmm, could be usable for development at least. won't win any 'sexy dev board of the month' contests, but hey its a dev board.
Exactly, the module handles most or all of the protocol level stuff internally so I'd expect a managed driver to perform ok or at least better than any UART based module....at the outset it might be too much for a managed 'driver'. well maybe. maybe not! I say this only because its' interrupt driven and I was concerned about latency, but then if it's handling the network stack, then it is also handling acks and retries so the host may be able to be more leisurely about servicing requests.
Yes, I have a couple of those boards and as I recall, the design makes pretty good use of the PCB space as it is bit I suppose one could always add a couple of layers....anyway I know the various ghi boards in dip form factors do, so it should be doable from a layout perspective.
I can imagine you'd display graphics or even video ;-)...ps hanzibal, I have been meaning to do your oscilloscope art, but I haven't been able to get to it yet, haha

I think I just fried mine Seems pwr_en is ground and it's supposed to be an input...

@Valkyrie-MT: Great to learn you've joined this party!
I was under the impression those structures were actually pretty well documented.

...or am I missing the point here?
EDIT: At the time of writing, I noticed that the TI wiki seems to be having some problems but the links have worked before so it's probably just a matter of time before the problem is solved.
EDIT: Links are ok again

Great, those are some really good guide lines!
Admittedly, I haven't read your posts all that thoroughly yet (it's late over here) and surely there are things to be discussed but just to be clear that I was merely picturing a really basic (yet powerful and versatile) Wifi board for the common Netduino user to benefit from, not the next "Wifi Ûbershield" :-)
Primarily, I was thinking a Netduino specific board with header layout to match. Heck, the world is overwhelmed by Arduino stuff as it is, and it's not like we would be making a zillion unit thing with a technical height that could withstand more than a week on eBay given every little peace of additional hardware adds to overall costs in terms of time and consequently that of gold.
Basically making a few simple mods to that github board (undoubtedly nice work) in order to get a cheap, quick and dirty wifi board for the whole Netduino family of boards (not excluding the mini) with a managed driver to go as I know of which the ancient lady warrior being extremely resourceful when it comes to the latter of things :-)
@ziggurat29: Have you ever considered politics or have they perhaps already got to you? SMD.
#51092 Spark Core (TI CC3000) Porting for Super WiFI Mini?

Looks like a nice board!
Yeah, the 5 x MOSFETs translate to and from 3V3 and Arduino 5V respectively. For Netduino projects they're not needed at all but there are hex converters if Arduino compatibility is required. There are some alternative pin routing that can be omitted as well.
Personally I wouldn't be soldering stuff onto such a fairly expensive board so I would put a standard 0.6" DIP24 IC holder for you know what (with the corresponding pins routed) instead of that prototyping area.
I don't see a 2.1 mm barrel connector for external power and I'd like to be able to use an external antenna so a uFL connector could be added.
If you guys like, I could tinker with a slightly different board incorporating the modifications suggested above or differently if you think otherwise would be better. I'm no RF designer but the mods would be quite small except for maybe the uFL connector.

You can usually ignore those warnings, vendors typically stress such things on samples to maximize the probability of users achieving success in evaluating the part. I'm pretty sure you can leave the bag open for years and it will still work and yield an ok product for hobby purposes.

What do you need to know?
Too bad there's no F4 in 48 pin package. I don't really see the point in talking to the Spark Core over UART, there are simpler and/or cheaper ways of doing that:
