Nucleo F412ZG
Overview
The Nucleo F412ZG board features an ARM Cortex-M4 based STM32F412ZG MCU with a wide range of connectivity support and configurations. Here are some highlights of the Nucleo F412ZG board:
STM32 microcontroller in LQFP144 package
Two types of extension resources:
ST Zio connector including: support for Arduino* Uno V3 connectivity (A0 to A5, D0 to D15) and additional signals exposing a wide range of peripherals
ST morpho extension pin headers for full access to all STM32 I/Os
On-board ST-LINK/V2-1 debugger/programmer with SWD connector
Flexible board power supply:
5 V from ST-LINK/V2-1 USB VBUS
External power sources: 3.3 V and 7 - 12 V on ST Zio or ST morpho connectors, 5 V on ST morpho connector
Three user LEDs
Two push-buttons: USER and RESET

System Clock
Nucleo F412ZG System Clock could be driven by internal or external oscillator, as well as main PLL clock. By default System clock is driven by PLL clock at 96MHz, driven by 8MHz high speed external clock.
Serial Port
Nucleo F412ZG board has 4 UARTs. The Zephyr console output is assigned to UART3. Default settings are 115200 8N1.
Network interface
Ethernet over USB is configured as the default network interface
Programming and Debugging
Nucleo F412ZG 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 or JLink can also be used to flash the board using
the --runner (or -r) option:
$ west flash --runner openocd
$ west flash --runner jlink
