The GSM device requires a 5V power source, however, it uses 3V on the RX and TX pins. So using a 3v pro mini is the easiest solution with an external 5V power source. This project provides the 5V power source to the GSM via a 5V Step Up Converter that is connected to two batteries. Is there a certain part of the section "Connecting to GSM A6" that confuses you, that I could help clarify? I've added schematic image which I have to hand, hopefully it will help, I don't have the complete one on me at the moment. I'll see if I can find that later. — You are receiving this because you authored the thread.
