Product Description The Arduino Nano V3.0 is a small, complete, and breadboard-friendly development board based on the ATmega328P. It offers nearly the same functionality as the Arduino Uno but in a significantly smaller footprint, making it the go-to choice for space-constrained projects and permanent installations. This version utilizes the CH340G USB-to-Serial converter for reliable programming via Mini-USB. Unlike the Uno, the Nano provides two additional analog input pins (A6 and A7), offering more flexibility for sensor-heavy applications. Its compact dual-inline package (DIP) design allows it to plug directly into a breadboard or a 30-pin IC socket for seamless prototyping.

Key Features

  • Ultra-Compact Design: Measuring only 45mm x 18mm, it fits easily into small enclosures, wearable tech, and compact robot chassis.

  • Breadboard Ready: Features 0.1" pitch headers that allow the board to be mounted directly onto a breadboard for stable circuit testing.

  • Extra Analog Pins: Includes 8 analog inputs (A0-A7), providing two more channels than the standard Arduino Uno R3.

  • Flexible Power Supply: Can be powered via the Mini-USB port, a regulated 5V supply, or an unregulated 6-12V supply through the Vin pin.

  • High Compatibility: Fully compatible with the Arduino IDE; simply select "Arduino Nano" and the "ATmega328P (Old Bootloader)" processor.

Technical Details

  • Core Processor: 8-bit AVR architecture providing 1MIPS per MHz throughput, balancing power efficiency and processing speed.

  • Mini-USB Interface: Robust Mini-USB port for programming and serial monitoring (requires CH340 drivers on most systems).

  • PWM Channels: 6 digital pins (D3, D5, D6, D9, D10, D11) support 8-bit Pulse Width Modulation for motor and LED control.

  • Communication Buses: Dedicated hardware support for I2C (SDA/SCL), SPI (MISO/MOSI/SCK), and UART (TX/RX) protocols.

  • Onboard Regulation: Features the LM1117-5.0V and 3.3V LDO regulators to provide stable power to internal logic and external sensors.

  • Reset Mechanism: Includes a top-mounted tactile reset button and support for auto-reset via software from a connected PC.

  • Status LEDs: Four integrated SMD LEDs for Power (POW), User Program (L - Pin 13), and Serial Communication (TX/RX).

  • Flash Storage: 32KB of flash memory (2KB used by bootloader) for storing compiled sketches and constant data.

  • SRAM Capacity: 2KB of internal SRAM for dynamic variable storage and stack operations.

  • EEPROM Access: 1KB of non-volatile memory for saving configuration settings that persist after power loss.

  • Logic Level: Operates on 5V logic, ensuring direct compatibility with standard digital sensors and 5V relay modules.

  • ISP Header: Standard 6-pin ICSP header for direct programming using an external AVR ISP programmer.

  • Pin Labeling: Clear silk-screened labels on the PCB surface for easy identification of digital and analog pins.

  • Soldering Versatility: Available with pre-soldered headers or loose pins for custom integration into narrow project spaces.

  • Oscillator Precision: 16MHz crystal oscillator provides accurate timing for time-sensitive tasks and serial baud rates.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: The Nano is ideal for 9V battery use. Connect the battery to the Vin pin (positive) and GND (negative). The onboard regulator will safely convert it to 5V. Avoid using 9V on the 5V pin, as it will bypass the regulator and destroy the ATmega328P.

  • 18650 Cell: For mobile projects, use two 18650 cells in series (7.4V) into the Vin pin. For a single 3.7V cell, use a 5V Step-Up (Boost) Converter and connect the output to the 5V pin.

  • IC & Capacitor Tip: If your Nano resets when using a servo motor, add a 100uF Electrolytic Capacitor across the 5V and GND rails. For driving multiple LEDs, use a 74HC595 Shift Register IC to expand your digital output pins while saving Nano I/O.

  • Related Products: We recommend pairing this with our Mini-USB Cables, HC-SR04 Ultrasonic Sensors, and MB102 Breadboards.
