ST Nucleo F030R8¶


The STM32 Nucleo-64 development board with STM32F030R8 MCU, supports Arduino and ST morpho connectivity.

The STM32 Nucleo board provides an affordable, and flexible way for users to try out new concepts, and build prototypes with the STM32 microcontroller, choosing from the various combinations of performance, power consumption and features.

The Arduino* Uno V3 connectivity support and the ST morpho headers allow easy functionality expansion of the STM32 Nucleo open development platform with a wide choice of specialized shields.

The STM32 Nucleo board integrates the ST-LINK/V2-1 debugger and programmer.

The STM32 Nucleo board comes with the STM32 comprehensive software HAL library together with various packaged software examples.

  • USB VBUS or external source (3.3V, 5V, 7 — 12V)
  • Power management access point
  • USB communication (LD1), user LED (LD2), power LED (LD3)
  • Virtual COM port
  • Mass storage
  • Debug port
  • IAR
  • ARM Keil
  • GCC-based IDEs

More information about STM32F030R8 can be found in the STM32F030 reference manual [2]

Supported Features¶

The Zephyr nucleo_f030r8 board configuration supports the following hardware features:

Interface Controller Driver/Component
NVIC on-chip nested vector interrupt controller
UART on-chip serial port-polling; serial port-interrupt
PINMUX on-chip pinmux
GPIO on-chip gpio
CLOCK on-chip reset and clock control
FLASH on-chip flash memory
WATCHDOG on-chip independent watchdog
I2C on-chip i2c controller

Other hardware features are not yet supported in this Zephyr port.

The default configuration can be found in the defconfig file: boards/arm/nucleo_f030r8/nucleo_f030r8_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.

Programming and Debugging¶

Applications for the nucleo_f030r8 board configuration can be built and flashed in the usual way (see Build an Application and Run an Application for more details).


Nucleo F030R8 board includes an ST-LINK/V2-1 embedded debug tool interface. This interface is supported by the openocd version included in the Zephyr SDK.
