I am in the hunt for a solar panel and charging circuit to power 3.3v microcontrollers, not together but separately. the boards i have in mind are
Arduino MKR WiFi 1010
Raspberry Pi Pico with LoRa
Arduino Nano RP2040 Connect
Adafruit Feather RP2040
Pimoroni Tiny 2040 with LoRa
If possible would love a way to solar charge the pi-top as a LoRaWAN Gateway if possible.
Does anyone know some off the shelf parts that will suit the job of powering the boards and Raspberry Pi?
I am looking for a way to charge the battery when its day time and run the micro controlelrs and let batteries take over when not enough power to run on solar power
I have no idea when it comes to solar power and would appreciate any help possible
