How can I connect the ac/dc converter to the board (nodemcu)?

Question

Arduino

I bought this converter for the project and now I want to connect it to the Nodemcu board via the Vin port.

Diagram of my converter:


I saw schemes of homemade chargers (on one end of the Micro usb for the board, and on the other two wires are soldered to + and - on the converter). But I don’t want to gut the charger, especially since I still need it for my phone.

And so it became interesting:
How to power the nodemcu from the converter through the vin port (to get stable 5V voltage at the output)?
Plus connect to Vin? Where is the minus? To the ground?
Or connect ground to NC?

If possible, write in more detail

My board (VIN and GND on the bottom left)

Answer 1

Yes, minus gnd.
Why don't you want to apply 5v to the usb input?
In general, there is a stabilizer on the nodemcu, like this, and it is connected exactly to vin
