Product Description The Arduino Nano R3 is a compact, breadboard-friendly microcontroller board based on the ATmega328P. Offering the same functionality as the Arduino Uno in a smaller form, it is ideal for projects where space is limited, such as wearables, IoT gadgets, robotics, and embedded systems. It features 22 I/O pins (14 digital, 8 analog), 6 PWM outputs, and a 16 MHz clock speed. The board can be powered via USB or an external power source (VIN), and is fully compatible with the Arduino IDE, making prototyping fast and easy.

FAQs Q1: What is the difference between Arduino Nano R3 and Arduino Uno?Nano R3 is smaller and breadboard-friendly, while Uno is larger and shield-compatible. Both use ATmega328P. Q2: Can it be powered by batteries?Yes, it can be powered through VIN (7–12V), USB (5V), or regulated 5V pin. Q3: Which USB cable does Nano R3 use?It uses a Mini-USB cable for both power and programming. Q4: Does it need a separate programmer?No, it has a built-in USB interface. Just connect and upload via Arduino IDE. Q5: Can I upload programs directly from Arduino IDE?Yes, it is 100% compatible with Arduino IDE, PlatformIO, and other environments. Q6: How many PWM pins are available?There are 6 PWM outputs (pins D3, D5, D6, D9, D10, D11). Q7: Is Nano R3 suitable for robotics?Yes, it can drive sensors, motors (with driver modules), and handle robotics projects. Q8: Can Nano R3 be used in IoT?Yes, with external Wi-Fi (ESP8266/ESP32) or GSM modules, it works perfectly for IoT. Q9: Is it beginner-friendly?Yes, it’s one of the most recommended boards for students and hobbyists. Q10: What accessories are commonly used with Nano R3?Breadboard, jumper wires, motor drivers, relay modules, and IoT modules.
