How to use ESPDUINO D1 R32 as a controller and select a library in Arduino IDE?

In the Arduino IDE you can configure this board as "DOIT ESP32 DEVKIT" or simply "ESP32 Dev Module". I have tested both cases.
Most importantly the autoreset works every time the code is uploaded.
The "digital" and "analogue" pins work in 3V3 logic - you need to keep this in mind before installing the overlays available for the Uno.
The downside is that I never manage to upload code at 921600, so I had to switch to 115200.
Board schematic attached (looks incomplete, but that's the only one on the manufacturer's website).

And most important: LED_BUILTIN is on GPIO 2 .

After replacing the USB cable, with a better and shorter one, I also uploaded at 921600 without problems, but I switched to 512000 just to be safe (I don't use the Arduino IDE).

It depends on the context of the call .
