@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.

You can put 100uf on each even 200uf would not be able to handle only one tx, so..
but you need them at least for coin cells.
you would need more capa to handle tx..but the more capa the more time they take for recharging, and the recharging if big, increase internal res of the coin cell and that's not so good too; to prevent this that would need a current resistor limiter..etc a whole balance!
On mine for instance, I have 100uF for coincell, 100uF for PIR and 86uf on radio. Fresh varta coincell 3.02V, after multiple presentation tx 2.85V if I remember, not so bad. but that's an homemade pcb.
Another notes, it's better to use ceramic capacitor (because of leakage, if you want to optimize), and better smd, but that's not your case I think.
@ozrex,
I don't want to assume your knowledge level. However the truth is that you will probably need to put together different bits and pieces from various threads in order to come up with your own custom solution (the A/C interface (IR) part, the battery part, etc...).
Maybe it is worth it to create your own new thread, or maybe you want to keep researching / trying on your own a little longer first. The latter is admirable, and is the way I usually do it, too. Some times to a fault in my own case. Don't suffer along in silence if you are struggling to find the information, make a thread instead. If it becomes too difficult you may give up. We all need some small successes along the way to keep motivated and keep it fun.
Probably best to create a new thread (I don't want to derail this one too much) but something you might want to look into is OpenMQTTGateway. I use it for my 433mhz, but it also supports RF, BLE, LoRa (and perhaps others in future) all on the same gateway! To me that was the way to go... And so far has been flawless for me.
