Is your feature request related to a problem? Please describe.
Onboard modules such as GPS and LoRa are known to draw power if left on, and potentially other sensors such as hsrc04, gas and temperature.
Describe the solution you'd like
Use an ammeter and the available manuals to find if they can be set to low power or if not determine whether a MOSFET is suitable to turn them off.
Describe alternatives you've considered
Let the battery drain?
