Arduino Pro Mini 3.3v - solar power - How?

Hello,

I will do a weather station in a few weeks based on this post. Looks simple ! But not tested myself for the moment.

Thanks @carlierd ,

That post is really interesting. Like him, my knowledges are very poor and I'm following suggestions to lean and apply on my own setups :)
Apart of this, I've seen he is using the BOARD1 (Micro USB 5V 1A 18650 Lithium Battery Charger Board With Protection Module), but still having the above doubts on which components to choose (and why), and how to wire it :-)

Any help is really appreciated, as always :+1:

Thanks,

Simon

I only bookmarked the thread and not started to analyse it !

I plan to finish inside node during christmas holidays so I will try the weather station node in January.
For the moment I need to finish my gateway.

Sorry guys if I "bump" again my thread.
I would be happy if someone could me at least suggest which solar panel should I search in terms of voltage and mA output and which batteries should be the best.

Thanks again and merry xmas ;)

About the battery:
A low power arduino runs several months with a 1000mA battery. As the sun hopefully rises every morning to charge the battery, you could use the cheapest one you can get.

I am very interested in this as well. I would like to charge an 18650 or 18350 to power remote sensors. Having the radio sleep untill needed would be a nice touch to conserve the battery as well.

hello,

the best for me are the 1W solar panel with either lipo or 18650. the best board is the ceech that does all in oneand has very low consumption, no led ☺

search the boards for posts on this, I will do a recap of the different methods to have self powered nodes for there are some issues as I have now with some lipo.

Where can I find this board?
BTW cannot do I the same with the above components?
Now I'm ok with the battery at least. A 1000mA should be enough ;)
And, 1W solar panel at 6V?

the ceech board used to be proposed in the hardware section here... shoule ask @hek where he has moved the link ?

Have a look here.

Thank you! I'll look on there.
