Re: Nextion with KA78T05

Check , raduino with nextion miight need 1amp odd. You cant work at 100% with input 12 or 13.5v.
If the 7805 input is just 3v above what you said is understandable.
Better try a genuine 78s05 it might manage.
All the best

Why would you need another regulator ? The LM7805 is designed for 1A output and the 5" Nextion display + Raduino uses about 500mA (per specs).
