This SIM800L breakout board is ideal for projects that needs to save space. In fact, this is the one I used when I created my own cellphone. This board draws a maximum of 2 A with an input voltage of 3.7 V to 4.2 V. This means you must not connect its pins directly to a 5 V Arduino! It doesn’t even run on 3.3 V.
N.B.: This product needs to be soldering before use.
