and ST morpho connectors
pinout.
Note: The D0 and D1 signals are connected by default to USART1 (MCU I/O PC4 and PC5). For details about how to
modify the UART interface, refer to Section 6.6.5 Virtual COM port (VCP): LPUART and USART.
Table 16 shows the pin assignment of each STM32G4 I/O on the ST morpho connector.
