I need to connect multiple data and address pins of a Z80 processor, which runs like the rest of my circuit on 5V, to the gpio pins of a mini wemos D1 Esp32. But I am not sure if the wemos can handle 5V input. I have tried to search for an answer but most of the answers I find are oppositions from each other. Some say it is ok to put 5V on the GPIO pins some say it will kill the chip.
So do I need to regulate the voltage or not?
