Arduino Nano V3.O (Copy)
The Arduino Nano V3.0 (Copy) is a small, complete, and breadboard-friendly development board based on the ATmega328P microcontroller. It offers the same functionality as the Arduino Duemilanove in a much smaller footprint, with a Mini-B USB connector and the CH340 USB-to-serial chip in place of the FTDI used on the official board. It features 14 digital I/O pins, 8 analog inputs, 6 PWM outputs, and a 16 MHz clock, making it ideal for compact projects, prototypes, and embedded applications.
لوحة Arduino Nano V3.0 (نسخة مماثلة) هي لوحة تطوير صغيرة ومتكاملة ومتوافقة مع لوحة التجارب، مبنية على المتحكم الدقيق ATmega328P. توفر نفس وظائف لوحة Arduino Duemilanove ولكن بحجم أصغر بكثير، مع موصل Mini-B USB وشريحة CH340 للاتصال التسلسلي بدلاً من FTDI المستخدمة في النسخة الأصلية. تحتوي على 14 منفذ دخل/خرج رقمي، 8 مداخل تناظرية، 6 مخارج PWM، ومذبذب بتردد 16 ميغاهرتز، مما يجعلها مثالية للمشاريع المدمجة والنماذج الأولية والتطبيقات المضمنة.
The Arduino Nano V3.0 (Copy) is a compact, fully functional development board built around the powerful Atmel ATmega328P microcontroller. Electrically identical to the Arduino Duemilanove and UNO, the Nano packs the same capabilities into a much smaller, breadboard-friendly form factor, making it the perfect choice for projects where space is limited.
Unlike the official Arduino Nano which uses the FTDI FT232RL chip, this version uses the widely available and reliable CH340 USB-to-serial converter. This means users must install the CH340 driver (available from our website) instead of the standard FTDI driver before programming the board. Once installed, the board is 100% compatible with the Arduino IDE and behaves exactly like an original Nano.
The Nano can be powered in three ways: through the Mini-B USB connector, via an unregulated 7–12V external supply on pin 30 (Vin), or through a regulated 5V supply on pin 27. The board automatically selects the highest available voltage source, simplifying power management in field deployments.
With 14 digital I/O pins (6 of which support PWM), 8 analog input pins, 32KB of flash memory, 2KB of SRAM, 1KB of EEPROM, and a 16 MHz clock speed, the Nano is more than capable of handling the vast majority of Arduino projects — from simple LED blinkers to complex sensor networks, robots, and IoT devices.
