@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:

[alexsh1]

@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.

[alexsh1]

Just waiting for some components to finalise it

[scalz]

@alexsh1
nice assembly :+1: oshpark i guess ??
I agree too, for PIR use, CR2450 is a minimum.
Well, with my tinkering and some stock in case, i usually get very quickly the free shipping..
but you can find these flash at Arrow for instance, they just need 20€ min order.
I guess you already have those, but for example,, coincell holders etc are not really cheaper at aliexpress etc..
Time to do some stock for stuff you need perhaps :)

[alexsh1]

@scalz yes, it is oshpark- I usually use them as the quality is exceptional. And typically I only need 3-4 pcbs anyway.
Unfortunately, I do not have oven and do not use smd stencil, which means the process is very long and manual. A lot of hot air fan work under the magnifying glass, but given this is not a board with too many components, it works.

You should get some commission from Arrow. I have just placed my order for eeprom and some parts ;))

[Sergio Rius]

Good job! Looking forward for a assembled version for buying. (NRF, of course :grinning: )

[Carywin]

@scalz I ordered some boards and components which are on the way, but I can't find the source code anywhere?
