Just a bare solar panel (actually 5V) soldered to a microUSB connector. The yellow LED on the Mayfly comes on in sunlight and goes off inside/in deeper shade and the battery charges.

We used them to power other micro controllers. It looks like both JST and USB inputs are connected to the same circuitry and I am curious about using our current hardware to power the Mayfly. I was just wondering if there was a specific reason this should not be used.

Does this method have the same protection (from overcharging the battery) as charging via the JST?
