Arduino UNO R3 (SMD) with USB Cable – ATmega328 – 14 Digital IO – 6 Analog Inputs – 16MHz Clock

The Arduino UNO R3 (SMD) with USB Cable is a powerful and easy-to-use microcontroller board ideal for students, hobbyists, and professionals. Built around the ATmega328 chip, it offers 14 digital input/output pins (6 with PWM output), 6 analog inputs, and a 16MHz clock speed for reliable performance.

With 32KB of flash memory (0.5KB used by bootloader), 2KB SRAM, and 1KB EEPROM, it provides ample storage for code and variables. The board operates at 5V, with a recommended input voltage of 7–12V (limits: 6–20V). Each I/O pin supports up to 40mA DC current, and the 3.3V pin can supply up to 150mA for connected modules.

This Arduino board is widely compatible with sensors, shields, and modules, making it perfect for projects in robotics, IoT, automation, and electronic prototyping. The included USB cable ensures easy programming and power supply from your computer.
