Features

The Arduino Uno SMD is a version of the Arduino Uno, but uses an surface mount version of the Atmega328P instead of the through-hole version. This version was made in response to a shortage in supply of the through-hole Atmega328P. The board is based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega8U2 programmed as a USB-to-serial converter.

Arduino Uno SMD R3

ATmega328P (SMD)
5V Logic
16 MHz
USB Type-B

Overview

The Arduino Uno SMD R3 is a classic, beginner-friendly microcontroller board built around the
ATmega328P in a surface-mount package. Functionally it’s the same as the standard UNO, but the
microcontroller is soldered directly to the PCB (SMD) instead of being socketed. This makes the board slightly
more compact and robust in production use. It’s ideal for education, prototyping, and embedded projects that
need reliable 5 V I/O, abundant community examples, and full compatibility with the Arduino IDE.

Key Features

Fully compatible with Arduino IDE (Windows/Mac/Linux).
14 digital I/O (6 PWM) + 6 analog inputs – perfect for sensors, LEDs, drivers, and shields.
On-board 16 MHz crystal, power regulation, and auto-reset over USB for easy uploading.
Robust 5 V ecosystem with thousands of shields, libraries, and tutorials.
SMD design improves durability for classrooms and installations.

Typical Applications

STEM education, labs, and workshops
Home automation prototypes (relays, sensors, keypads)
Robotics (motor drivers, encoders, ultrasonic sensors)
Data logging (temperature, humidity, light) with SD shields
Wearables / art installations (LED matrices, addressable strips via level shifting)

Power & Compatibility Notes

Power via USB Type-B, VIN (7–12 V), or the 5 V pin (regulated 5 V only).
Compatible with most UNO R3 shields; check pin usage conflicts (D0/D1 for UART, D10–D13 for SPI on ICSP).
For 3.3 V sensors (e.g., ESP8266 modules), use a bidirectional level shifter.

Package Includes

1× Arduino Uno SMD R3 board
1× USB Type-B cable (if included by seller; check variant)
Quick-start reference card (optional)

Notes

The SMD version is more compact and cost-effective than the DIP version, but the microcontroller is not easily
replaceable by hand. For classrooms that frequently damage chips, consider the DIP (socketed) UNO.
