2.1 How to send SMS and turn on GPS

BATTERY OUT:

Module SIM	ESP32 (Power)
Vin	5V USB /external source
GND	GND
TX	GPIO 16 (UART2 RX MCU)
RX	GPIO 17 (MCU UART2 TX)
EN (Pull low for shut down module, default pulled up)	Floating (Depends on hardware),

Note: Vin prioritizes 5-12V external power supply (SIM module). (connect to 5V of ESP32 must ensure the USB port has enough current)

The GND pin of the ESP32 and the SIM module must be connected together to communicate with UART.
