Arduino Uno R3 SMD Board Kit Without USB Cable

Start Building with the World's Most Popular Microcontroller Board

The Arduino Uno R3 SMD is the surface-mount version of the iconic Arduino Uno — the go-to development board for beginners, students, and engineers alike. Featuring the ATmega328P-AU SMD chip, it offers the same proven performance as the DIP version in a more compact, professional form factor.

Key Specifications

• Microcontroller: ATmega328P-AU (SMD)
• Operating Voltage: 5V
• Input Voltage: 7–12V (recommended), 6–20V (limit)
• Digital I/O Pins: 14 (of which 6 provide PWM output)
• Analog Input Pins: 6
• Flash Memory: 32 KB (ATmega328P) — 0.5 KB used by bootloader
• SRAM: 2 KB | EEPROM: 1 KB
• Clock Speed: 16 MHz
• USB Interface: CH340 USB-to-Serial chip
• Form Factor: SMD (Surface Mount Device)

What’s in the Box

• 1 × Arduino Uno R3 SMD Compatible Board
• Note: USB Cable NOT included

Why Choose the SMD Version?

The SMD variant uses a surface-mounted ATmega328P chip, making it slimmer and more resistant to physical shock — ideal for embedded installations, compact enclosures, and production prototypes. It is fully software-compatible with the standard Arduino Uno R3.

Compatible With

• All standard Arduino shields and libraries
• Arduino IDE (Windows, macOS, Linux)
• Sensors, motors, displays, relays, and virtually any Arduino module

Tip: You’ll need a USB Type-A to Type-B cable (not included) or a CH340 driver for first-time setup on Windows.
