I want to use a T-Echo running Meshtastic as a remote repeater. I have two questions.
Can the T-Echo be charged without damage by a 2.5w 5v solar panel?
If the battery dies on the T-Echo, could a 2.5w 5v solar panel in full sun wake it up?

Would there be any other potential issues in using a T-Echo as a solar powered remote repeater ?
