Arduino Uno R3 (SMD Version)

The Arduino Uno R3 (SMD Version) is an open-source microcontroller board featuring the ATmega328P SMD chip. It is functionally identical to the regular Arduino Uno (DIP version) but uses a surface-mount design, making the board slimmer and more durable.

This version is ideal for users who want the full power of Arduino Uno in a space-efficient form factor. It is widely used for robotics, IoT, DIY electronics, and academic projects.

Key Features:

• Microcontroller: ATmega328P (SMD)

• Operating Voltage: 5V

• Input Voltage (recommended): 7–12V

• 14 Digital I/O pins (6 PWM output)

• 6 Analog input pins

• Flash Memory: 32 KB

• SRAM: 2 KB, EEPROM: 1 KB

• Clock Speed: 16 MHz

• USB Type-B interface for programming & power

• Auto-reset function for easy upload

• Compact SMD design for reliability

Differences from DIP Version:

• Uses ATmega328P in SMD package (non-removable)

• Slimmer and lighter design

• Same performance and pin layout

Applications:

• Robotics & automation projects

• IoT and smart devices

• Educational purposes

• DIY electronic prototyping

• Long-term embedded projects
