Regarding the RAK19007, when using the onboard solar charging circuit, I understand that the solar panel must be 5 volts.
What is the maximum current from the solar panel that the solar charging circuit can handle? Put another way, what is the maximum wattage solar panel that can be used?
Usually the maximum charge is determined by the battery?
What is the maximum size (AH) LiPo battery that can be used with the RAK19007?
Thank you
