Connections and IOs
The Nucleo F303K8 Board has 1 GPIO controller. This controllers is responsible for input/output, pull-up, etc.
Board connectors:
Default Zephyr Peripheral Mapping:
The Nucleo F303K8 board features an Arduino Zero V3 connector. Board is configured as follows:
UART_2 TX/RX : PA2/PA15 (ST-Link Virtual Port Com)
I2C1 SCL/SDA : PB7/PB6
SPI1 CS/SCK/MISO/MOSI : PA_4/PA_5/PA_6/PA_7
LD2 : PB3
System Clock
The Nucleo F303K8 System Clock can be driven by an internal or external oscillator, as well as by the main PLL clock. By default the System Clock is driven by the PLL clock at 72 MHz. The input to the PLL is an 8 MHz internal clock supply.
Serial Port
The Nucleo F303K8 board has 2 UARTs. The Zephyr console output is assigned to UART2. Default settings are 115200 8N1.
Programming and Debugging
The Nucleo F303K8 board includes an ST-LINK/V2-1 embedded debug tool interface.
Flashing
The board is configured to be flashed using west STM32CubeProgrammer 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
