Changing the default UART pins

[Palonso]

Hi,

I've seen in many places that you can change the UART pins to any other available pin with practically no restriction (apart from being output capability for TX), but I would like to know if there is any issue with the performance of it.

For example, I'm working with WROVER-B, is the same if I set the UART0 for GPIO1 and GPIO3 as for the GPIO27 and GPIO14?

Best regards,
P

You get an extra clock cycle of delay from the pins but uart is asynchronous anyway
