Which board should I select for ESP32-WROOM-32E?

[ClarkLee]

Dear All,
I've start to use the ESP32 with Arduino IDE.

All instruction for install to use ESP on Arduino is cleared.
Compile and download is OK.

But not work the GPIO.

Below is the code. It's simple. Just swing the GPIO.
I've select the board 'ESP32 Wrover Module'.
Which board should I select for ESP32-WROOM-32E board? I also tried 'ESP32 Dev Module'. I'ts same.

Arduino IDE 1.8.15. and all other's default settings.


Please advice to me. Thank you.

Does your terminal give you any output? If so, can you copy/paste it here?

It's definitely not the "WROVER" module; that's another chip. I believe that the "ESP32 Dev Module" is what you want to select.

I also have similar problem.
Try ESP32 Beetle.
I repeat project for MPPT solar charger, which was at shematic and code on ESP32-WROOM32, but I have ESP32-WROOM-32e chip. Genuine selection was ESP32 DEV module but I HAVE trouble, I discover at internet for ESP32-WROOM32 to select such ESP32 Beetle at Arduino board selections. It works better in my project.
