Description

The NUCLEO-G431KB is an open development board centered on the Arm® Cortex®-M4 core of the STM32G431 microcontroller. It provides a complete prototyping environment for embedded engineers and makers, integrating the ST-LINK debugger directly on-board to streamline firmware flashing and debugging via a Micro-AB USB connection. The board’s design emphasizes ease of use and rapid iteration.

With its Arduino Nano V3 form factor connector, the platform offers straightforward hardware extensibility, allowing developers to leverage a wide range of specialized sensor, actuator, and communication shields. This makes it suitable for prototyping IoT endpoints, industrial control nodes, and smart device concepts. The board is supported by the STM32Cube ecosystem, including middleware and code generation tools, and is compatible with major IDEs like IAR Embedded Workbench, Keil MDK, and GCC-based environments.

Frequently Asked Questions

How do I program the NUCLEO-G431KB board?

The board is programmed using the integrated ST-LINK/V2-1 debugger. Connect it to your PC via the Micro-AB USB port. Install the STM32CubeIDE or your preferred IDE (Keil, IAR). The board will appear as a mass storage device; drag-and-drop compiled .bin files, or use the debug interface for direct flashing and live debugging through the ST-LINK's Virtual COM port.

What power supply options are available for this development board?

The board can be powered in three ways: via the ST-LINK's USB VBUS (5V), through an external 5V-12V supply connected to the E5V and GND pins on the Arduino connector, or via the 3.3V and 5V pins on the same connector. The on-board switching regulator and LDO provide the necessary core voltages. Ensure total current draw does not exceed the regulator's limits when using shields.

How do I use Arduino Nano shields with this STM32 Nucleo board?

The board's morpho connector is mechanically and electrically compatible with Arduino Nano V3 shields. Align the shield's pins with the female header on the NUCLEO-G431KB. Pin mapping follows the Arduino Nano layout, but you must use the STM32Cube HAL or LL libraries to configure GPIO, ADC, I2C, SPI, and UART peripherals, as the pin functions are defined in your STM32CubeMX project, not by the Arduino IDE framework.
