Have you installed the ESP32 board manager via the IDE Preferences screen?

You need this URL included in the list.

https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

Once that is done, restart the IDE. You should then see the ESP32 boards in the board manager from the editor.

Thank you red_carKarma: 200+.
I have these set, thing is which one pick, there are so many ESP32 there.

for example the ESP32CAM, select AI Thinker and ESP32 DEV both work.

How about the ESP WROOM?

Did you try this board?

[shanren]

thanks.
I'll try it.
BTW. what the short sentences meaning : ESP32 gpio numbers instead of physical pins?

[red_car]

Generally you are only interested in the GPIO pins numbers (purple in the diagram below).

Physical pins relate to the pins on the actual chip itself. These are obviously important, if for example, you are making your own PCB, but generally if you are using a module like above you don't really need to know this detail.

Great!
Thank you.
