I am looking into potentially running these boards on a solar charging system and was wondering what size battery would be required to continue operation for a period of time for situations where light is limited. I cannot find any numbers about current draw in low power states for either of the boards and was wondering if anyone happened to know.
jgeckard,
What boards are you thinking of running?

My apologies… should have specified. I am using a sparrow dev kit so I was wanting to power a sparrow reference sensor node with a solar charging system.
Hi @jgeckard,
Assuming you are using the provided Sparrow Reference Sensor Node from Blues, it does come with a 2xAAA battery holder. Honestly my personal recommendation would be to drop 2x Lithium AAA batteries in there and not worry about solar at all.
