Connect Solar Panel To Breadboard Arduino

[vanepp]

@EmilM21

Would it work if I add up a 12v module charger(allows me to stack up batteries) with a 12v solar panel and then use Reo rand to reduce the output to 7v for the arduino ?

Yes, except you need to change the reo rand for a buck regulator (the reo rand will only increase the voltage not reduce it.) These ones are common and have a fritzing part:

Mini-360 DC-DC Buck converter

It is reasonably trivial to make a modified part. The existing one matches ones I bought from ebay, and in fact all the ones I looked at after typing a search for “mini 360 dc-dc” on ebay in fact show as being 17x11. If you have a pointer to the one you want I can change it easily enough. I assume you want the wider spacing on the silkscreen on pcb view (as I can’t see it mattering particularly anywhere else)?
