Cranberry v4.1 Charging

The Cranberry Weatherbox is the third generation environmental sensor module, capable of measuring barometric pressure, humidity, temperature, and solar irradiation. The module is integrated as part of a weather sensor network that communicates with a central server. The main motivation for the design of Cranberry is to improve upon the hardware of the first generation weatherbox, Apple. This is accomplished mainly through the implementation of a more efficient power system and an overall reduction in size and cost.

However, the original design contains numerous hardware design problems, and is currently not operational. Therefore, the Cranberry team is responsible for troubleshooting the problems of this design, as well as implementing changes which will improve the design as a whole.
