Hi all.

I'm using STM32H747I-DISCO bord.

According to user manual, Pin No.1 in Pmod™ is connected to PA11/PA0.

And Pin No.1 in STMod+ is also connected to PA11/PA0.

Then can I use PA11 as USART1_CTS via Pmod™ Pin No.1, and PA0 as GPIO via STMod+  Pin No.1 concurrently?

Thanks in advance.

    No You cannot, the two pins are connected together:
