96The default configuration can be found in the defconfig file:
97``boards/arm/nucleo_c031c6/nucleo_c031c6_defconfig``
98
99Connections and IOs
100===================
101
102Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as
103input (with or without pull-up or pull-down), or as peripheral alternate function. Most of the
104GPIO pins are shared with digital or analog alternate functions. All GPIOs are high current
105capable except for analog inputs.
106
107Default Zephyr Peripheral Mapping:
108----------------------------------
109
110- UART_2 TX/RX : PA2/PA3 (ST-Link Virtual Port Com)
111- LD4       : PA5
112
113For mode details please refer to `STM32 Nucleo-64 board User Manual`_.
