This is makes it easier to use these in simulation, plus it avoids duplication. The only downside I see is that more UARTs get defined than a board supports, but no existing code should break (no UARTs get renamed for example).

// Sometimes the board is not detected even when the board is connected to your computer.

// To solve this, place a jumper wire between the REC and GND pins, then connect the board to your computer.
