used by STM32 on Nucleo board and connected to ST-LINK
2.2 UART and GPIO connection options
As stated previously, the connection between the SPWF01SA and the STM32 Nucleo
boards is made via a four wire UART (with hardware flow control) and some GPIOs. A
multiple connection arrangement offers maximum modularity (See Table 4). The alternative
pins could be useful in case of conflicts with additional X-NUCLEO expansion boards.
