UNO R3 Rev3 Board Compatible with Arduino 

Product Overview
Bring your ideas to life with our Arduino UNO R3 Rev3 Compatible Board a drop-in replacement for the classic UNO R3 that combines proven reliability with modern USB connectivity. Built around the 16 MHz ATmega328P MCU and CH340G USB interface, this versatile 5 V development board is perfect for everything from beginner experiments to complex IoT deployments.

Key Features & Benefits

  • ATmega328P MCU @ 16 MHz
    Industry-standard processing power for smooth sketch execution and real-time control.
  • CH340G USB-Serial
    Plug-and-play USB connectivity on Windows, macOS, and Linux no external USB-serial dongle required.
  • Compact Footprint
    78 × 53 × 15 mm fits easily into enclosures, wearable projects, and tight PCBs.
  • Flexible Powering
    7–9 V DC via barrel jack or 5 V via USB; onboard regulator ensures a stable 5 V rail.
  • 14 Digital I/O (6 PWM)
    Drive LEDs, servos, and motors with precise PWM control on pins 3, 5, 6, 9, 10, and 11.
  • 6 × 10-Bit Analog Inputs
    Read sensors from thermistors to photoresistors with 0–1023 resolution.
  • 32 KB Flash Memory
    Includes 2 KB for the bootloader, leaving 30 KB for your sketches.
  • Robust I/O
    40 mA per pin (200 mA total) to power modules and small loads directly.
  • Standard Headers
    Compatible with the vast ecosystem of Arduino shields and breadboard wires.
