Reliable Arduino Platform

The Arduino Uno R3 is one of the most widely used microcontroller boards for learning electronics, programming and embedded systems. It is based on the ATmega328P microcontroller and provides a straightforward combination of digital and analog I/O, making it suitable for everything from beginner projects to practical automation and control applications.

Powerful I/O for Prototyping

The Uno provides 14 digital input/output pins, including 6 pins that can be used for PWM output, as well as 6 analog input pins. This makes it easy to connect LEDs, buttons, displays, motors, sensors, relays and other electronic components. Communication interfaces include UART/USART, I2C and SPI for connecting external modules and peripherals.

Easy Programming

Programming the Arduino Uno is simple through the Arduino development environment and USB connection. Its ATmega328P microcontroller runs at 16 MHz and provides 32 KB of flash memory, 2 KB of SRAM and 1 KB of EEPROM, giving you enough resources for a wide variety of control, sensing and automation projects.

Expandable and Versatile

The Uno is designed to work with Arduino shields and a large ecosystem of sensors, modules and accessories. It is an excellent choice for robotics, home automation, IoT prototypes, educational projects, instrumentation and general-purpose embedded development.

DIP and SMD Variants

This product is available with either a DIP or SMD version of the ATmega328P microcontroller. The DIP version uses a removable through-hole chip, making it convenient to replace the microcontroller or use it in standalone projects. The SMD version has the microcontroller permanently soldered to the board, providing a compact surface-mount implementation.
