Rs232 using Uart2?

I have a project that I am porting from an esp32 DEV board.
I currently use UART2 for RS232 communication between boards.

I want to use the inbuilt SD card, and also have RS232, but on the pinout I don't see U2TXD.
Is there a UART available other than the one for the USB that doesn't interfere with the SD card or the inbuilt USB?

Thanks
Jim

Which board exactly is that? We don't have board called "esp32 DEV". Can you find the board you got at our web-site and share link to the product page here?

Sorry - I was porting the project from a generic DEV board to an ESP32-POE.
I have it working now using UART1

Thank you.

Does using the ethernet port stop TaskScheduler from working?

Glad you got it working.

I have no idea about what you asked but I also don't have experience with TaskScheduler. Maybe also ask in the official ESP32 forums about that.
