Any available UART of the STM32 application can be connected to the CN3 connector of
the ST-LINK part.

NUCLEO-L476RG for connection of UART1 to the host.
UART1 RX PC5 is routed via Morpho Connector CN10 Pin 6 to CN3 TX of
NUCLEO-L476RG ST-LINK.
UART1 TX PC4 is routed via Morpho Connector CN10 Pin 34 to CN3 RX of
NUCLEO-L476RG ST-LINK.

With this setup, on the PC side, two Virtual COM ports are available with potentially two
different serial channels:
1. Nucleo-F302R8 UART2 (native default VCP) to COM4
2. Nucleo-F302R8 UART1 (VCP through Nucleo-L476RG) to COM8
