7.5 CN7 and CN10 ST morpho connectors
CN7 and CN10 ST morpho connectors are male pin headers accessible on both sides of the board. All signals
and power pins of the STM32WL MCU are available on the morpho connectors. These connectors can also be
probed by an oscilloscope, logical analyzer, or voltmeter.
Figure 24. ST morpho connectors
Note: The D0 and D1 signals are connected by default to USART1 (MCU I/O PB6 and PB7). Refer to
Section 6.6.5 for details about how to modify the UART interface.
Table 18 shows the pin assignment of each STM32WL I/O on the ST morpho connector.
