Easy solar power question

Postby capo12 » Thu Apr 26, 2012 12:14 pm

Hi

I'm trying to run my arduino uno using solar panel. I already have a Lipoly charger, a 6v solar panel, and a 3.7v 2700 mAh lipoly (see below for exact specs). In order to run my arduino, can I just connect the + cable from the charger "load" to the 5v power pin in the arduino, and the - cable from the charger "load" to the arduino ground?

USB LiIon/LiPoly charger - v1.2 (http://www.adafruit.com/products/259)
Medium 6V 2W Solar panel - 2.0 Watt (http://www.adafruit.com/products/200)
Lithium Ion Polymer Battery - 3.7v 2700mAh - (http://www.adafruit.com/products/328)

Thanks

No, because the output of the "Load" terminals is going to be in the 3.7-4.2v range. You can use a Mintyboost to boost the voltage back to 5v as in this example:
