Hey, so, I want to power up my arduino circuit using Li-ion batteries charged by a solar panel. I need some advice on what DC-DC Boost Convertor to buy so I can take my voltage up to 7V(for the VIN input) Right now I’m using Lm2596 but it can only lower voltage.  
Input voltage is 3,5-3,6V.

Here is one I made for someone:

> Hey, does anyone has a library for this module or something similar? I just need a 5v solar charger module so that I can connect my 18650 lithium battery, solar panel and arduino to it. [Screenshot\_1] This is the link to the module description if it helps: [CN3065 Mini Solar Charger Module](https://components101.com/modules/cn3065-mini-solar-charger-module)

found via a google search for “fritzing part solar cell charger” as I remember making it but not what it was called. There are probably more as well.
