Arduino Uno SMD R3 Compaitable

The Arduino Uno SMD R3 Compaitable is a versatile microcontroller board based on the ATmega328P in SMD package. It features the same 14 digital I/O pins, 6 analog inputs, and 16 MHz clock as the DIP version with a more compact layout. Perfect for beginners and advanced makers alike.

Key Features

• ATmega328P SMD microcontroller with 32KB flash memory
• 14 digital I/O pins (6 can be used as PWM outputs)
• 6 analog input pins for sensor reading (10-bit ADC)
• 16 MHz clock speed for fast execution
• USB programming via onboard CH340
• Wide shield compatibility with hundreds of expansion boards
• Surface-mount design for slimmer profile

Technical Specifications

Applications

• DIY electronics projects and interactive prototypes
• Robotics including line followers and obstacle avoiders
• Home automation systems and IoT devices
• Sensor monitoring and data logging
• Educational STEM learning and maker workshops
• LED control and addressable lighting projects

Important Notes

• SMD version is functionally identical to DIP version
• Do not exceed 5V on any I/O pin to prevent permanent damage
• Maximum current per I/O pin: 40mA (recommended 20mA)
• Use external power supply for high-current loads
• Compatible with Arduino IDE and most Arduino shields
