+# Solar + Cellular Overview
+The solar + cellular iterations of the frog sensor allow the sensor to operate in a wider variety of environments, as they do not require a power and wifi source. This is intended to enable a wider range of data gathering
+
+# Versions
+| Version | Description |
+| :---: | :--- |
+| Solar V1.0 | Desmond’s final submission to Hackster contest. Technically functional and testable, but worth making a few updates before production. |
+| Solar V1.1 [WIP] | Slightly updated version of Desmond’s submission. Changes include (non-exhaustive): Updated footprint mapping for Q5 - Objectives: Gather useful data, test |
+| Solar V1.2? [future] | TBD. Solves a more specific problem as defined by stakeholders and longer-term project objectives, e.g. data gathered is of 'scientific rigor,' enables 1 sensor per satellite pixel, deployable with targeted strategy in mind (e.g. doesn't require soldering if that's not realistic for target group, swappable sensors if that increases uptake) |
