I just bought ESP32-GATEWAY, but there is no UEXT connector as described in the web site.
How to connect UEXT to RS232C module?


ESP32-GATEWAY has no UEXT. It is visible in the pictures. If there is any misleading information about UEXT around our web-site we shall remove it.

That is not an point of worry tho. Free GPIO pins are led to the CON1 at good 0.1" step. Any free GPIO can be used for the RS232 data signals. You can easily solder wires, pins, or attach a header there (it is even easier at the bottom since no components and the table of pins is there too).
