Changing the default UART pins

Postby Palonso » Thu May 28, 2020 5:32 pm


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,

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