Arduino Mega + SIM808 GSM + GPS Module + Program Switch ON without pressing Push Button? I am new to IOT and tried out integration and a small test code with an Arduino Mega + SIM808 + GSM + GPS Module. It works fine with the SIM808 Library.

My requirement is to put it in an enclosure, but when the power restarts, for some reason we have to manually start the SIM 808 + GPS + GSM Module. Can we control it from code? Can we do a software trigger from Arduino code?

Maybe if we have some pins to connect and trigger the power on. Kindly provide inputs/suggestion for this module.

If you are aware of some module that can be started through code kindly suggest.

Here's one reference I found for a different module with Software Trigger.
There is a simple way of power the module without pressing the button. There is pin call D9 at the bottom right corner of the module. Just power the pin by Arduino digital pin or 5v pin around 3, 4 seconds. Then it will power the whole module. No need to press the press switch. Make sure you connect power(9V-12V) to the board and provide 5V and GND to the sim808 module. below figure shows the pin D9
