Hi,
nice projet. I am very interested in it.
But why you are using 5 V and not 3.3 V? The ATmea328 works with 3.3 V too and the NRF have to use 3.3 V.
The only restriction on 3.3 V is the clock limitation for the Atmega (8 MHz). But with no crystal it don't care.
For example you could use an HLK-PM03 instead of HLK-PM01 and remove the linear voltage regulator. So you get more space an everything have the same voltage level.
And another point is, it is recommended to use a capacitor (0.1 ยตF) to ground for each voltage pin (Vcc, Avcc, Aref).
@chbla said in Multiple uses battery RFM69 node:
Can anyone suggest a source for the parts? Are there any sources that you can upload the files by any chance?
If you mean can you upload a BOM to a company and then it generates a basket of the items, then i know that farnell and maybe digikey do this. But i only use this feature that is built into EAGLE pcb designer, so i'm not sure if they support it directly on their websites, might be worth a look.

@vlad I am having the same issue. Where did you change keepalive timeout to a long time?
Essentially, what file did you edit, what parameter and to how long?
