Most boost converters require more current than a mini or micro solar panel can deliver. This project skirts that issue by repeatedly charging and discharging a capacitor at lower voltages to provide the needed current to drive the boost converter. It can work with even very low currents provided at voltages of 0.85v and above. The resistor settings are configured to charge 2.7v supercaps.

If you enable the ENABLE pin, then the project will function like an ordinary boost converter, with the same limitations therein. Therefore, even though the ENABLE pin is exposed, I recommend you either don't use it or else use it just for monitoring purposes only.

The purpose of the project is to charge a supercap, which can then power your mysensor node. It is not intended to power your mysensor node directly without a supercap.

As always, if you have any suggestions for improvements, please post.
