Arduino UNO R3 SMD Variant Improved Version

The Arduino UNO SMD is an enhanced version of the classic Arduino UNO, featuring a surface-mounted ATmega328P instead of the through-hole variant. Designed to overcome supply shortages of the through-hole ATmega328P, it delivers the same performance with improved assembly and reliability.

Features:

• Simple programming using the open-source Arduino IDE
• Beginner-friendly microcontroller ideal for learning and prototyping
• Preloaded libraries for most sensors and application modules
• SMD version with surface-mounted ATmega328P, chip is non-removable
• Maintains the same performance as the original UNO R3

Technical Details:

• Based on the ATmega328P datasheet
• 14 digital input/output pins (6 PWM capable)
• 6 analog inputs
• 16 MHz crystal oscillator
• USB connection for programming
• Power jack for external supply
• ICSP header for in-circuit programming
• Reset button for easy restarting

Compatibility:

Unlike previous Arduino boards, the UNO R3 SMD uses the ATmega8U2 as a USB-to-serial converter instead of the FTDI chip, ensuring seamless connectivity with modern systems.
