@scalz Would also be very interested in buying assembled modules. But why no more RFM69?

[alexsh1]

@mpp I suppose depends on which battery and what sensors - there are a few options here.

[alexsh1]

@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?

[Anticimex]

@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.

[alexsh1]

@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..

[alexsh1]

@scalz ATSAM D21 is already compatible with MySensors, whereas ATSAM L21 may be in the pipeline. So for now, we all are stuck with SAMD.

Looking forward to your stl

[Konrad Walsh]

Phenomenal!

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

[alexsh1]

@Konrad-Walsh You buy PCBs (10 0r 15 of them).

[Konrad Walsh]

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

[alexsh1]

@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.

[Konrad Walsh]

@alexsh1 Thank you

[alexsh1]

@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

[scalz]

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

[Nca78]

@scalz could you give an idea of the price ? I'm curious :)

[Carywin]

Where might I find the source code?

[alexsh1]

@Carywin a source code for what? There are many combinations of sensors.
I am sure @scalz can help :-)

[bjornhallberg]

Still very much interested in buying the board with RFM69 footprint! Just saying!

[alexsh1]

@scalz do you mind me asking where you bought PIR lens, eeprom, and most important that fancy small antenna??? Thanks

[scalz]

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.
  An example of link for the lens:
