I know that I can run a UART on pins 0,1. I need to run a second bidirectional async serial port and would prefer to use a second UART rather than bit-bang. Is it possible to run a UART on pins 2,3 as well? Circuit Python and the Metro M4 are both relatively new to me. The doc I was able to find was not clear on the subject.
Thanks in advance.

Re: 2 UART on Metro M4
There's a script here that will print out available TX/RX pins:
