Hello - I am putting together a circuit that will power an arduino and a sim800 sms module or an a6 sms module. I am mounting it on blank pcb board. I am using a mosfet circuit to send power to the sms bouard. Both sms module's specs say they will draw 2 amps during sending. I have read that 2 amps is not even measureable on an amp meter because it happens so fast. How do I know if my pcb board will handle this amperage and how do I know if the wire will handle the amperage? I am confused about wire gauge for chassis use and power transmission. They are hugely different. I would like to use 24 gauge wires.
Please give me your thoughts.
