STM32 Nucleo64 C031C6
A Nucleo-64 development board with STM32C031C6 MCU: ARM Cortex-M0+ processor, 32 KB Flash, 12 KB RAM running at 48 MHz.
Onboard LED
The Nucleo-C031C6 has an onboard user LED (LD4), attached to GPIO pin PA5 (D13). The LED is lit when the pin is driven high.
You can also use the LED_BUILTIN constant to reference the LED in your Arduino code:
pinMode(LED_BUILTIN, OUTPUT);
digitalWrite(LED_BUILTIN, HIGH);
See Blink for a complete code example.
