3.PIN OUT
ESP32 has fewer pins than commonly used processors, but it doesn't have any problems reusing multiple functions on
pins.
Warning: The pin voltage level of the ESP32 is 3.3V. If you want to connect the ESP32 to another device with an
operating voltage of 5V, you should use a level converter to convert the voltage level.
Power Pins: The module has two power pins +5V and 3.3V. You can use these two pins to power other devices and
modules.
