Product information

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

Key specifications

  • Microcontroller: ATmega328
  • Clock speed: 16 MHz
  • Memory: 32 KB flash (ATmega328), 2 KB SRAM, 1 KB EEPROM
  • Digital I/O: 14 pins (6 PWM outputs)
  • Analog inputs: 6
  • Operating voltage: 5 V
  • Recommended DC input: 7–12 V
  • Dimensions: 53.4 x 68.6 mm
  • Certifications: RoHS, FCC, CE
  • Manufacturer part number (MPN): A000073
  • EAN: 8058333490137

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.
