* @endcode
* This links to the third entry in the `arduino_pinmap` array.
*
* - a define `ARDUINO_UART_DEV` that defines the UART to use as the Arduino
* primary serial port (default UART_DEV(0)):
* @code{c}
* #define ARDUINO_UART_DEV (UART_DEV(3))
* @endcode
*
* In addition, you have to add the 'arduino' feature to the board. For this,
* just add `FEATURES_PROVIDED += arduino` to the 'other features' section in
* your board's `Makefile.features'.
