I'm finalizing the nrf24 version because it's a nice board, that would be too bad for nrf24 user

Did you finish the nrf24 version @scalz ?

[scalz]

@tonnerre33 sorry for delay. yep, sure i finished it a while (rev 1.1 nrf), never ordered it, i use rfm for this node. but i'll upload this week oki

[tonnerre33]

@scalz Thx a lot ! I tried to replace the transmitter myself but the routing is too hard for me.

I'll try to check the schema before order the board ;)

[Bigbug]

This looks like an awesome unit! Is there a way to buy this with components assembled? Looks like a lot of work to solder all those smds..

[pointbre]

I also wish I could buy assembled ones.

[tomtastic]

Likewise, to be able to buy assembled would be great

[alexsh1]

@scalz hi, excellent sensor! Do you know if the atmega328 memory is enough? You must have a large sketch for all sensors + signin

[scalz]

@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..

[mpp]

How long can you get these running on a single battery?

[bjornhallberg]

@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.

[scalz]

@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.
