RX/TX pinout for node mcu ESP32s wroom

[KASR]

Hi,

I have an ESP32 from node mcu (see the figure below for the pinout and the board specifics.

I think the pinout is not exactly the same as what's mentioned in the readme. Is my understanding that the pin 21/25 mentioned in the readme are the TX0 and RX0 pins in the figure below?

In other words, would this be the correct connection:
