3.3V Solar Power supply - AA rechargeable battery allowed

Description

Sometime a hidden part of a catalog can reveal a jowel! Behind its sober appearance, here is a very interesting product.

This Olimex product was designed for the MSP430 kit but it can also been used in your own projects to create an autonomous low power 3.3v device.

Under the roof, this module is composed of a solar panel (2.4V 80mA) and a DC/DC step-up converter that bring the voltage to 3.3V.
In option, a socket can hold a 1.2V AA Rechargeable battery. The battery is loaded with the solar panel et will be used to power the DC/DC converter (when there no sun available).

Considering the characteristics, this product shoud be used with low power project... but if you wanted to use this mocule with a low power microcontroleur (or other)... with deep-sleeping microcontroleur then this product will be an interesting approach for autonomous project.
