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. Thanks Felix
