My solar powered #meshtastic outdoor router in progress.
Today I soldered everything together and will test how efficient this setup is.
It's a 5v solar panel with a charge module and a 18650 battery connected via USB with 0.9-5v mobile booster. This should step in if available and load the internal 18650 battery.
I use TBeam v1.1 esp32 for this project with bt, wifi, lora and GPS included. For the outdoor solution, bt and wifi gets disabled.
