I’m attempting to create a weather station in order to collect data for a machine learning project. Seen as the 1010 has a built in LiPo charging circuit, I’m thinking that I will be able to use that to wire in an 18650. Then use a solar panel and a voltage regulator into the USB port to charge the battery. Am I along the right lines here? Or do I still need a solar charging circuit? I’d also like to be able to use the output of the solar panel as a sensor.
