Product details

Overview

NUCLEO-F031K6 from STMicroelectronics is an STM32 Nucleo-32 development board built around the STM32F031K6T6 32-pin ARM Cortex-M0 microcontroller, featuring on-board ST-LINK/V2-1 debugger/programmer, a user LED, reset button, ARDUINO® Nano V3 expansion connector, and Micro-AB USB interface for programming and virtual COM port. It supports flexible power via USB VBUS or external sources and ships with STM32Cube MCU Package libraries.

For engineers reviewing the NUCLEO-F031K6 datasheet, NUCLEO-F031K6 pinout, NUCLEO-F031K6 application, or NUCLEO-F031K6 equivalent, this board enables rapid prototyping of low-power embedded control systems using STM32F0-series peripherals including 12-bit ADC, 16-bit timers, and I²C/SPI/USART interfaces - all without requiring external debug hardware.

Technical Context

The NUCLEO-F031K6 implements a complete evaluation platform for the STM32F031K6T6 MCU, integrating ST-LINK/V2-1 firmware that provides mass storage device (MSD), virtual COM port (VCP), and SWD debug capabilities over a single Micro-AB USB connection. Its ARDUINO Nano V3 footprint enables plug-and-play compatibility with standardized shields for analog sensing, motor control, or wireless add-ons.

Board-level design includes a 32-pin LQFP package footprint for the target MCU, onboard 3.3 V LDO regulation, and jumper-selectable power sourcing between ST-LINK VBUS and external supply - ensuring stable operation during firmware development, peripheral validation, and low-power mode testing.

FAQ

Does the NUCLEO-F031K6 require an external debugger?

No. The board integrates ST-LINK/V2-1 firmware on-chip, enabling full debugging, flash programming, and virtual COM port functionality via its single Micro-AB USB connection - eliminating the need for additional debug probes or adapters during development.

Which IDEs are officially supported for the NUCLEO-F031K6?

STMicroelectronics officially supports STM32CubeIDE (cross-platform), IAR Embedded Workbench® (Windows only), and Keil MDK-ARM (Windows only, with free version for Cortex-M0/M0+ cores). All integrate directly with the on-board ST-LINK/V2-1 interface for seamless build-debug-deploy workflows.

Can the ARDUINO Nano V3 connector be used with commercial shields?

Yes. The board implements a fully compatible ARDUINO Nano V3 pinout (including 5 V-tolerant digital I/O, analog inputs, and hardware SPI/I²C/UART signals), allowing direct use of off-the-shelf shields for displays, sensors, motor drivers, and RF modules without level-shifting or adapter boards.

What is the role of the 24 MHz crystal oscillator on this board?

The NUCLEO-F031K6 does not include a 24 MHz crystal oscillator; that feature is specific to the NUCLEO-G431KB (MB1430). This board relies on the STM32F031K6's internal 8 MHz RC oscillator for system clock, with optional external high-speed crystal support via the MCU's HSE pins - but no populated crystal is present on the NUCLEO-F031K6 PCB.
