Alphabetize these for ease of finding things.

How about renaming these, because TX and RX are traditionally used for UART? On CPX and other boards, we use these names:

THe GPIO28 pin alias was removed. Was that intentional? If so remove the line 114 comment.

If this is not true anymore, just remove.

I made requested changes. the comments in pins.h have been updated and remain relevant for future maintenance of the code. |

The RP2040 Explorer Badge used traditional IR capabilities. These use GP0 and GP1 which were previously anticipated to be exposed for UART. They are no longer exposed as pins and are dedicated to the RI emitter and IR receiver.
