the MIMXRT1050-EVK uart pin (in the arduino port) is it the UART1 instance ?

[wassimhammami]

Hi,

I have a two MIMXRT1050-EVK boards and I want to communicate between them using UART.

As indicated in the user's guide (picture attached to this post) there is a UART pin in the arduino expansion port, so I want to use it. But I don't know in which instance this pin is attached to ?

(UART1 or UART2 or ...)

Thanks

The UART3 port is used in the Arduino interface of the i.MX RT1050 EVK board.

Have a great day,
Artur
