Product Description
The Arduino Nano R3 is a small and versatile development board based on the ATmega328P microcontroller, designed for compact embedded projects and rapid prototyping. Featuring a 16 MHz crystal oscillator, multiple digital and analog I/O pins, and onboard USB-Mini interface for programming and power, the Nano R3 is ideal for space-constrained designs, wearable systems, and breadboard prototypes.
This version is sold without the USB cable, allowing users to choose their preferred cable type or reuse existing ones. Compatible with the Arduino IDE, it supports all standard Arduino libraries and shields that fit the Nano footprint. Typical applications include sensor interfacing, robotics control, data logging, home automation gateways, IoT endpoints, and educational prototypes.
