Hello @TheAlphaGhost

I think the code you uploaded is for M5Stack and not M5Core2.

Please use #include <M5Core2.h> at the top and remove M5.Power.begin() which is required for M5Stack only.

#include <M5Core2.h> void setup() { M5.begin(); M5.Lcd.print("Hello World"); } void loop() { }

You probably will need to download and install the proper library for M5Core2 as well.
