Yep! 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.

I’ll go ahead and order some JST connectors just to be safe. Thanks!

We have some solar panels (6v) that are attached to micro USB ports. 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.
