Mini Weather Station

it depends if you want the high power version or use the standard rfm69w at 17dBm and you will be fine to use it down to 1.8V (of course it will work also a little over 3.3V too)

Great device. Why not use a solar power station, like in a solar garden light. Not very good at power equations. What else you going to hook to this? rain gauge, wind speed .... Thanks
