@alexsh1 thx :)
memory ok if sketch optimized (radio driver footprint too) and without much debug msg.
V2 will improve memory, cost and device size (will be 9in1 this time so i needed more mem) but for nrf24 networks only. i should release it soon if i can get rid of a little sw bug..@scalz atmega328 is only good for simple sketches nowadays. I am struggling with a simple temp/hum/baro sensor with signing and debug as It runs on low memory and the sensor freezes after a few hours. I suppose we have to move to SAMD.
Do you have the STL file for the box please? -

Do you have the STL file for the box please?@alexsh1 regarding low memory problems, debug is intended for just that; debug. Once deployed, you can disable debug to ensure the longevity of your program. Probably the sketch eventually dies due to stack shortage.
Do you feel secure today? No? Start requiring some signatures and feel better tomorrow ;)

@Anticimex Completely agree. Having said that I have a few nodes where I left debug purely for convenience. I do not want to re-flash the node to debug it in case need be. Right now I am in the process of changing the GW and may need to see node's debug.

@alexsh1
I agree with you about 328 and 8bits. And that's a while i've done a board for these ;)
I won't use it in v2 though, tiny 9in1... not possible!
I also have custom SAMD boards, missing time to release those one too, but imho these mcu are not ultra low power (SAML is).I'll publish stl this week..

Phenomenal!
I have a stupid question.. clicking buy on the page.. what exactly does that buy you>?

@Konrad-Walsh You buy PCBs (10 0r 15 of them).
-
I am sorry.. I should have been more clear...
When you say PCB.. Is that a fully assembled product with all the mentioned sensors? Or is it a board and you add sensors to it..Please excuse my ignorance

@Konrad-Walsh Click on the link and see it yourself ;-)
PCB means a bare board and not a ready product. You have to procure parts and assemble it. -

@alexsh1 Thank you
@Konrad-Walsh said in 💬 MyMultisensors:
you
No problem.
@scalz There is a lot of interest from others to have an assembled sensor. Maybe as a suggestion, you would be interested talking to Itead or similar guys to get it arranged?
Personally, I am comfortable assembling an SMD board down to 0605 (though it is more difficult with the fan). My preference would be 0805 and up -
thx for the interest though :)
for the moment, the quotation i got was not so great imho.. oki i'll try again with other fabhouse for this one ;) as v2 will cover nrf only -
Still very much interested in buying the board with RFM69 footprint! Just saying!
-
@scalz do you mind me asking where you bought PIR lens, eeprom, and most important that fancy small antenna??? Thanks
sorry to be so quiet actually :)
I buy most of my ic at electronic suppliers like Mouser, Digikey, Arrow etc.- the flash is AT25DF512C-MAHN-T . But for coincells, ota+rfm69 is a bit too much power hungry, imho..
- the small pcb antenna is ANT-868-USP but it was for fun, as a simple wire antenna works as well and is cheaper.
- PIR and PIR lens are from aliexpress or ebay. PIR is LHI968. And fresnel type is 8120.

@scalz Thank you. I do shopping at those sites as well if I do a large order, but delivery charge is just killing if I need to order 1-3 items.
I am going to try 2450 with your board. It has 600mAh so I am hoping that using eeprom is fine with this coincell. Regarding 2032, I agree with you. I have a node, which consumes 5-6uA (with watchdog) and I had to disable the LED to use it with coincell. It just drains too much energy from a low capacity battery.
Yes, simple wire would work fine, but ANT-868-USP is just looking very tidy.
