Nucleo F334R8
Overview
STM32 Nucleo-64 development board with STM32F334R8 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 does not require any separate probe as it 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 F334R8 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 Port Com)
UART_3 TX/RX : PB10/PB11
I2C1 SCL/SDA : PB8/PB9 (Arduino I2C)
SPI1 CS/SCK/MISO/MOSI : PB6/PA5/PA6/PA7 (Arduino SPI)
PWM_1_CH1 : PA8
USER_PB : PC13
LD2 : PA5

Programming and Debugging
Nucleo F334R8 board includes an ST-LINK/V2-1 embedded debug tool interface.
Applications for the nucleo_f334r8 board configuration can be built and
flashed in the usual way (see Building an Application and
Run an Application for more details).
Flashing
The board is configured to be flashed using west STM32CubeProgrammer [4] runner, so its installation is required.
Alternatively, OpenOCD, JLink, or pyOCD can also be used to flash the board using
the --runner (or -r) option:
$ west flash --runner openocd
$ west flash --runner jlink
$ west flash --runner pyocd
Flashing an application to Nucleo F334R8
Connect the Nucleo F334R8 to your host computer using the USB port, then build and flash an application. Here is an example for the Blinky application.
# From the root of the zephyr repository
west build -b nucleo_f334r8 samples/basic/blinky
west flash
You will see the LED blinking every second.
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_f334r8 samples/basic/blinky
west debug
