The default configuration can be found in the defconfig file: ``boards/arm/nucleo_g071rb/nucleo_g071rb_defconfig`` Connections and IOs =================== Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as input (with or without pull-up or pull-down), or as peripheral alternate function. Most of the GPIO pins are shared with digital or analog alternate functions. All GPIOs are high current capable except for analog inputs.
