## Summary description

The Arduino UNO SMD Rev3 is a versatile development board featuring the ATmega328 microcontroller with a frequency of 16 MHz. It offers 32 KB of flash memory, 2 KB of SRAM, and 1 KB of EEPROM. With a compact size of 53.4 x 68.6 mm, it operates at 5 V and supports a DC input voltage of 7-12 V. The board is RoHS, FC, and CE certified, making it a reliable choice for various projects.

## Long description

The Arduino Uno SMD R3 is a development board based on the ATmega328 microcontroller running at 16 MHz. It includes 14 digital input/output pins (6 of which support PWM), 6 analog inputs, 32 KB of flash memory, 2 KB of SRAM, 1 KB of EEPROM, a USB connection, a power jack, an ICSP header and a reset button. The board is powered via USB, an AC-to-DC adapter or a battery and conforms to RoHS, FCC and CE standards. The R3 revision introduces an ATmega16U2 USB-to-serial converter and the updated 1.0 pinout while preserving the core features of the Arduino Uno line.
Advantages
The Arduino UNO SMD Rev3 offers a compact, well-documented platform with broad community support and compatibility with Arduino shields. Its updated R3 features—ATmega16U2 USB-to-serial chip, additional SDA/SCL and IOREF pins, and a stronger reset circuit—improve USB handling, I2C access and shield compatibility. The board’s 5 V operating voltage, 7–12 V recommended DC input range and standard form factor make it suitable for prototyping and embedded projects.
Suitable for
Learning microcontroller programming and electronics
Prototyping sensors, actuators and interactive projects
Developing small automation and control systems
Using standard Arduino shields and libraries

How to use
Connect the Arduino UNO SMD R3 to a computer using a USB cable to program it via the Arduino IDE, or supply external power through the DC jack or a suitable battery within the recommended voltage range. Install or select the ATmega328 board profile in the Arduino IDE, write or load a sketch, compile and upload. Use the digital and analog pins for sensors, actuators and communication interfaces; employ the ICSP header for low-level programming if required.
Usage recommendations
Use USB power during development and when uploading sketches; when deploying in standalone applications, use a regulated 7–12 V DC adapter. Observe the 5 V logic level for connected modules and shields, and consult shield documentation for IOREF compatibility. Avoid exceeding the absolute maximum ratings of the microcontroller pins.
