Microcontroller boards are compact, integrated platforms that combine a microcontroller unit (MCU) with essential peripheral interfaces, power regulation, and connectivity options. Designed for embedded applications, they enable rapid prototyping and deployment of automation, IoT, and control systems.

These boards typically feature:

• MCU Core (8-bit, 16-bit, 32-bit ARM Cortex-M, RISC-V, etc.)

• Digital and Analog I/O Pins for interfacing sensors, actuators, and modules

• Communication Interfaces such as UART, I²C, SPI, CAN, and USB

• On-board Power Supply handling (5V, 3.3V LDOs)

• Optional Wireless Connectivity (Wi-Fi, Bluetooth, LoRa, etc.)

Popular examples include Arduino, ESP32, Raspberry Pi Pico, and STM32 Nucleo boards, which are widely used in industrial automation, robotics, home automation, and educational projects due to their open-source ecosystems and extensive library support.
