ST Nucleo F030R8
Overview
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.
More information about the board can be found at the Nucleo F030R8 website 1.

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.
Board connectors:
Default Zephyr Peripheral Mapping:
UART_1 TX/RX : PA9/PA10
UART_2 TX/RX : PA2/PA3 (ST-Link Virtual COM Port)
I2C1 SCL/SDA : PB8/PB9 (Arduino I2C)
I2C2 SCL/SDA : PB10/PB11
SPI1 NSS/SCK/MISO/MOSI : PB6/PA5/PA6/PA7 (Arduino SPI)
SPI2 NSS/SCK/MISO/MOSI : PB12/PB13/PB14/PB15
USER_PB : PC13
LD1 : PA5
For mode details please refer to STM32 Nucleo-64 board User Manual 4.
Programming and Debugging
Applications for the nucleo_f030r8 board configuration can be built and
flashed in the usual way (see Building an Application and
Run an Application for more details).
Flashing
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.
Flashing an application to Nucleo F030R8
Here is an example for the Blinky application.
# From the root of the zephyr repository
west build -b nucleo_f030r8 samples/basic/blinky
west flash
You will see the LED blinking every second.
If using the C-01 board, select revision ‘1’ that supports the board.
# From the root of the zephyr repository
west build -b nucleo_f030r8@1 samples/basic/blinky
west flash
Debugging
You can debug an application in the usual way. Here is an example for the Blinky application.
# From the root of the zephyr repository
west build -b nucleo_f030r8 samples/basic/blinky
west debug
Again you have to use the adapted command for C-01.
# From the root of the zephyr repository
west build -b nucleo_f030r8@1 samples/basic/blinky
west debug
Board Revisions
Nucleo F030R8 has some version of board variants. STM32 Nucleo-64 board User Manual 4 mentions to Nucleo board variants.
The board version MB1136 C-01 or MB1136 C-02 is mentioned on the sticker, placed on the bottom side of the PCB.The board marking MB1136 C-01 corresponds to a board, configured as HSE not used.The board marking MB1136 C-02 (or higher) corresponds to a board, configured to use ST-LINK MCO as the clock input.
Using revision 2 adapted for C-02(or higher) as default when not explicitly selecting revisions. If using the C-01 board, select revision 1. Please see Flashing section.
