STM32 Development Board
🔧 STM32 Nucleo Development Board – 5V/3.3V
Overview
The STM32 Nucleo board is an affordable, versatile development board based on STMicroelectronics STM32 microcontrollers (e.g., F3, F4, F401, F411). It integrates an onboard ST-LINK debugger/programmer, Arduino-compatible headers, and supports multiple IDEs. Perfect for beginners and pros building embedded applications, IoT devices, or motor control systems no.mouser.com+13st.com+13labprojectsbd.com+13.

Getting Started
Connect to PC via USB cable → board gets power (5 V/3.3 V).
Open STM32CubeIDE or Mbed Online IDE.
Create a new project—MCU gets auto-detected via onboard ST‑LINK.
Write a “blink LED” program and upload directly—no extra programmer required.
Applications
Prototyping with sensors, actuators, and communication modules
Motor control, robotics, and power electronics
IoT gateway, edge computing, and environmental monitoring
Real-time data acquisition with RTOS
Learning embedded C/C++ development and debugging
