***Please use a 5.0 V external power source when using an Arduino Pro 4G Module (EMEA / GNSS Global) or any other mPCIe modules due to their high power consumption. This is important for maintaining a stable power supply to the Portenta SOM and the carrier, particularly for extended periods of use.***
