Arduino UNO R3 ATmega328P CH340G

ATmega328P Microcontroller Core: Powered by the classic ATmega328P 8-bit processor running at 16MHz, delivering high performance for beginner and intermediate electronic builds.

Cost-Effective CH340G USB Driver: Integrates the reliable CH340G USB-to-Serial converter chip for effortless programming and serial debugging over standard USB.

100% Arduino IDE Compatibility: Fully compatible with the official Arduino IDE, software libraries, and existing open-source C/C++ code sketches.

14 Digital I/O & 6 Analog Input Pins: Equipped with 14 digital input/output pins (6 supporting PWM output) and 6 analog inputs for interfacing with sensors, motors, and displays.

Standard UNO R3 Shield Layout: Features standard pin header geometry to ensure seamless mounting with official and third-party Arduino expansion shields.

PCB Construction: Built on a durable multi-layer FR-4 glass epoxy printed circuit board with clear silk-screened pin labels and sturdy DIP socket architecture.

Power & Voltage Tolerances: Accepts 5V DC via USB connection or 7V–12V DC through the onboard DC barrel jack or VIN pin. Do not exceed 20\V input to prevent damage to the voltage regulator.

Handling & Driver Requirements: Install the CH340 driver on your computer prior to first setup; practice standard anti-static procedures when handling exposed circuit board terminals.

Environmental Limits: Operating temperature range is -10°C to +60°C. Keep protected from static discharge, metal shavings, and liquid moisture.

Budget-Friendly Prototyping Workhorse: Market as the most affordable, essential starting board for students, educators, and hobbyists taking their first steps in robotics and coding.

High-Value UNO Alternative: Position as a cost-effective alternative to official boards that offers identical circuit performance at a fraction of the cost.

Recommended Cross-Sell Add-ons: Pair with USB Type-A to Type-B Cables, Solderless Breadboards & Jumpers, and Sensor Starter Kits.

Wide Application Utility: Excellent choice for building desktop automation nodes, LED displays, motor drivers, and school STEM projects.
