Minimal design thoughts

@tbowmo
Sorry I was a bit unclear. I would like to buy all components as a package from you/mysensors. Preferably assembled, but I would also accept if you sell it unassembled (pcb+components). I would rather not have to source the components myself :)Btw, have you measured the actual power consumption? Sleep vs temp/hum measurement?
-
I haven't measured supply current, as I don't have the equipment to do that. I am looking at getting the uCurrent gold from eevblog, but it's expensive to import it to Denmark.
It will probably not be offered as a kit. Too much work from my/our part :-)
-
Soo .. this like a breadmix ? :) All we have to add is the sensors ?
-
You already got an ucurrent? I had planned to import an extra one from Australia for you :) (thought that we might be able to save some $ if we ordered 4-5 units).
But as so many other things i got away from it again :(
Unfortunately I only come to Copenhagen these days, visiting a client.

"ATSHA204A sot23 footprint on board"
So does that mean this run will not have the ATSHA204A populated?
-
@ServiceXp
We haven't started production yet, I'm still waiting for the latest prototype pcb to arrive from China, before I can make the (hopefully) last prototype before "mass production". Which also means I have to find the atsha204 somewhere, so I can test it.
And yes I know mouser has it, but I don't need that much more from them, so will have to pay a big handling/shipping fee to them

@tbowmo Have you looked on AliExpress. A quick search seems to suggest that could be a viable alternative. Try some different search combinations though ... their search engine sucks. "ATSHA204" wont find "ATSHA204A" for instance when I try.
Wont be quick though, and the Chinese New Year is coming up ...

I can part with a SOT23 ATSHA204A if necessary. They can also be sampled from Atmel in small quantities for free (that's what I did).

@hek It took three days from order confirmation to shipment notification. I don't recall the transit times but it went out with DHL WW Express so it should be pretty fast. Say 5-10 working days tops.
Do you feel secure today? No? Start requiring some signatures and feel better tomorrow ;)

hmm what is the sample quantity limit?

@tbowmo I don't remember. But I got at least three (don't think I requested more since at the time I was not sure it would meet my personal demands, nor if the MySensors community would accept it). Since it is now kind of "official" I guess it has :)

ok, I'll try and get some samples then.
Has there been any work done to support easy initialization of the keys on new devices?

@tbowmo That's already done. Available in development branch. I will update it to support devices without UART in the near future. Check libraries/sha204/examples/sha204_personalizer
Auto-generation of keys is supported as well as manually contributed ones (all devices in the same environment needs to share a key). All necessary personalization for MySensors usage is done (default settings are fine) and locking of both configuration and data sections are suppored (only configuration section is mandatory to lock).
