I wish Board selector to accept any board type not defined in the built in list.
In this example dialog will not work because I wrote ESP32 wroom 32 board type, which is not in the list.
The compiler needs to known the specifics of the board you are using.
You can change the boards displayed by adding or deleting boards in Arduino. (Tools/Boards/Boards manager)
) - If you have more than url you can separate them by comma.
2- Arduino IDE >> Tools >> Boards >> Boards manager >> scroll down to added board above >> highlight it >> click install
3- After successful installing, you will get the added board in board type list in B4R
