After designing the connection diagram between the processor and the 4G chip, the connection part is not clear, so it will be separated to easily change the connection in case it cannot be programmed.
UART is used, the power part is separated and tested after the test circuit works, the use of power from existing components is also acceptable, no need to design now, the important thing is The processor and 4G chip work stably first.
The project will start making PCB samples to test this schematic in the next sessions.
