The Arduino Nano board

The Arduino Nano board provides more or less the same functionality of the Arduino Duemilanove but in a more compact design. Comparing to the Arduino Duemilanove board, the Arduino Nano board lack a DC power jack and has a mini-USB connector instead of a standard USB.

Technical specifications of the Arduino Nano board

The technical specifications of the Arduino Nano board are as follows:

  • Microcontroller ATmega328
  • Operating Voltage (logic level): 5 V
  • Input Voltage (recommended): 7-12 V
  • Input Voltage (limits): 6-20 V
  • Digital I/O Pins : 14 (of which 6 provide PWM output)
  • Analog Input Pins: 8
  • DC Current per I/O Pin: 40 mA
  • Flash Memory 32 KB (ATmega328) of which 2 KB used by bootloader
  • SRAM: 2 KB (ATmega328)
  • EEPROM: 1 KB (ATmega328)
  • Clock Speed: 16 MHz
  • Dimensions: 0.73" x 1.70"

Powering the Arduino Nano

The Arduino Nano can be powered via the Mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.

Programming the Arduino Nano board

The Arduino Nano can be programmed using the free Arduino software (download). Select "Arduino Diecimila, Duemilanove, or Nano w/ ATmega168" or "Arduino Duemilanove or Nano w/ ATmega328" from the Tools > Board menu.

The ATmega328 microcontroller on the Arduino Nano board comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header.
