Hi! Nice video. I have some questions and hope you reply.

I am trying to connect it with Flame Sensor. But I already used 5V for the Flame sensor. What am I supposed to do in order to feed the SIM800L? Do I have to buy an external power supply(like 3.7V, 4V, 4.4V) and converter?

or Connecting to Ground(GND) is enough to run it?
