Product Details
Arduino Nano V3.0 (ATmega328P)
The Arduino Nano is a compact, complete, and breadboard-friendly board based on the powerful ATmega328P microcontroller. It offers nearly the same functionality as its larger sibling, the Arduino Uno, but in a much smaller package. This tiny footprint makes the Nano the go-to choice for projects where size and weight are critical, such as wearables, small robots, and embedded systems, allowing you to move from a breadboard prototype to a finished product with minimal effort.

- ATmega328P Microcontroller: The same reliable and well-documented 8-bit processor found in the Arduino Uno, running at 16MHz.
- Breadboard-Friendly Design: The DIP-style package with 0.1" pin headers allows the Nano to be plugged directly into a standard breadboard for easy prototyping.
- Rich I/O: Provides 14 digital I/O pins (6 of which can be used as PWM outputs) and 8 analog input pins.
- Onboard USB Connectivity: Features a Mini-USB port for programming, serial communication, and power. Uses the common CH340 or FTDI FT232RL chip for USB-to-serial conversion.
- Fully Arduino Compatible: Program it seamlessly using the Arduino IDE and access thousands of existing libraries and code examples.
- Flexible Power Options: Can be powered via the Mini-USB port, a 5V regulated external power supply, or a 7-12V unregulated supply to the VIN pin.
💡 Applications
- Wearable Technology: Its small size is perfect for integrating into clothing and accessories.
- Compact Robotics: The ideal brain for small robots where every gram and millimeter counts.
- Sensor Nodes: Build a network of small, independent sensors for data collection.
- Rapid Prototyping: The ultimate board for quickly building and testing circuits on a breadboard.
- Embedded Control Systems: Integrate it directly into custom PCBs for a permanent, compact solution.
