UART on the T-Relay (4) board? #12

Closed wkearney99 closed 1 year ago

wkearney99 commented 1 year ago

Is it possible to use any of the IO pins on the T-Relay (4) board for UART communications? The usual ones for UART0 (IO3, IO1), 1 (IO9,IO10) and 2 (IO16, IO17) are not brought out onto the header.

This comment on the T-Display made me wonder if something similar is possible for the T-Relay. https://github.com/Xinyuan-LilyGO/TTGO-T-Display/issues/47

Yes. You can reuse IO as many times as you want
