Arduino UNO R3 SMD Variant With Cable

The Arduino UNO R3 SMD Variant with cable is a compact and reliable microcontroller board, designed as an alternative to the traditional UNO R3. Instead of the through-hole Atmega328P, this version uses the surface-mounted (SMD) Atmega328P chip, making it equally powerful but more cost-effective and widely available. This board delivers the same performance as the original Arduino UNO and is perfect for beginners, hobbyists, and professionals. With a simple USB connection, you can program and power it directly from your computer, or use an external adapter or battery for standalone projects.

Highlights

• 14 digital input/output pins, including 6 PWM outputs
• 6 analog input pins
• 16 MHz crystal oscillator
• USB connection for programming and power
• Power jack for external supply
• ICSP header for direct microcontroller programming
• Reset button for quick restarting

The UNO R3 SMD features the CH-340 USB-to-serial converter, providing reliable connectivity for uploading sketches and communication. Unlike the original DIP version, the Atmega328P chip here is soldered directly onto the PCB. While the chip cannot be easily replaced, performance remains identical to the standard UNO R3.
