Switching power to a GSM Module - what to use?

Other Hardware General Electronics
1

The SIM800L GSM/GPRS module needs a 2A 5V power supply, which I need to switch for a few seconds every 10 minutes or so, in order to send out an HTTP request.

I would like the logic to be handled by an Arduino. Which component can I use to switch the power to the SIM800L?
A simple electrical relay is too large for my use case - GPS tracker

Consider using one power supply and a MOSFET to turn on the GSM module. Power supplies do not like to be switched on and off all the time.

The sim800L can be powered up/down using its PWRKEY pin.

I suspected it was actually that simple. :+1:
