Arduino UNO Rev3 SMD — ATmega328, 14 Digital I/O, USB, AC-to-DC Power Jack A000073
Available in stock (152)
Key Features
- ATmega328 Microcontroller — Reliable 8-bit processor in SMD form, ideal for embedded projects of all sizes
- 14 Digital I/O Pins — 6 configurable as PWM outputs for motor and LED control
- 6 Analog Inputs — Read sensors and variable signals with ease
- USB Connection — Program and power the board directly from your computer, no extra hardware needed
- AC-to-DC Power Jack — Supports standalone operation with a wall adapter or battery
- ATmega16U2 USB-to-Serial — Faster and more reliable than FTDI-based boards
- ICSP Header — Enables direct in-circuit programming for advanced use cases
- 16 MHz Ceramic Resonator — Stable clock source for consistent timing performance
- SDA & SCL Pins (R3 Pinout) — Full I2C support placed near AREF for easy shield compatibility
The Arduino UNO Rev3 SMD (A000073) is the surface-mount edition of the world's most popular microcontroller board. Functionally identical to the standard UNO Rev3 (A000066), it features the ATmega328 in SMD package — making it a great choice for projects where a lower-profile board is preferred. Like all UNO Rev3 boards, it includes the updated R3 pinout with dedicated SDA/SCL pins, a stronger reset circuit, and the ATmega16U2 for USB-to-serial communication.
Simply connect it to a computer via USB or power it with an AC-to-DC adapter or battery to get started immediately. The UNO is fully compatible with the vast Arduino shield ecosystem and is the reference platform for the Arduino IDE — making it one of the easiest boards to find libraries, tutorials, and community support for.
Ideal For
- Beginners — The most documented and supported Arduino board available
- Prototyping — Breadboard-friendly layout with standard shield compatibility
- STEM Education — Widely used in classrooms and coding curricula worldwide
- Makers & Hobbyists — A reliable workhorse for any DIY electronics project
- Low-Profile Builds — SMD package suits projects with tighter component clearance
