Arduino Uno SMD Rev3

The Arduino Uno Rev3 SMD is a versatile microcontroller board based on the ATmega328P. It features 14 digital input/output pins, of which 6 provide PWM output, and 6 analog inputs, making it suitable for a wide range of electronics projects and prototyping.

Powered by a 16 MHz ceramic resonator, the board operates at 5 V with a recommended input voltage between 7 and 12 V. It includes a 3.3 V output regulated supply capable of delivering up to 50 mA. The built-in LED connected to digital pin 13 allows easy testing and debugging.

The USB-to-serial communication is handled by an ATmega16U2 chip, replacing the older 8U2, improving reliability and performance. The board supports SPI, TWI (I2C), and external interrupts on pins 2 and 3, expanding its connectivity options.

Constructed with an epoxy material, the board measures 68.6 mm in width and 53.4 mm in depth, weighing approximately 25 grams. It includes essential components such as a USB connection, power jack, ICSP header, and reset button.

As open-source hardware, the Arduino Uno Rev3 SMD encourages customization and learning, making it an excellent choice for hobbyists, educators, and professionals alike.
