Change the circuit so that the board can be powered by a battery.
Change the circuit to utilize the internal charging circuit inside the sim808.
Change the buck converter configuration so that the output voltage is 4V. and add a Linear regulator to drop voltage to for the STM32.
4V input will be necessary for the SIM808 if it is used to charge a battery.
Add a 2 pin JTS connector for battery input.
