Help with Amica WiFi board circuit

Good day! On this circuit can someone bring a little clarity, because searching in google does not help.

I have an Amica WiFi board that needs 3.3v to run and a voltage level shifter. They are both made in KiCad, but on the circuit for the shifter it has 1npn and 1pnp transistor, but the name of the second transistor is the same as the first. So there is a mistake. Can anyone tell me how this circuit works please, as its confusing to me.

I don't know what its ment to be. That's why I ask does anyone know a anything about this circuit? And about the Amica WiFi module (NodeMCU) as I can't find a valid data sheet.

Note the pin numbers. I suggest that when I Google that part number I'll find its a dual mosfet in an 8 pin package.

Edit: yup. Just Google it.
