i`m wondering how exactly is this shield powered https://wiki.dfrobot.com/SIM800C_GSM_GP ... KU_TEL0089
I know i need to connect external power supply to my Arduino Uno, bot how this power goes to the shield? Are there any dedicated pins that i shouldnt use?

2021-01-05 17:27:18 This shield is the power obtained by connecting with Arduino. When using this shield, Arduino needs external power supply instead of just connecting to the computer. This shield does not have an additional power supply interface 347945801
