Nano 328(Arduino Compatible)

Model : MCA03328A

Initial Weight : 9.00g


Availability: In stock


    The Nano 328 is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.0) or ATmega168 (Arduino Nano 2.x).It have an integrated on-board USB. As the function, It has almost all the analog and digital pins that the UNO or Duemilanove has and the same function as Duemilanove or UNO. This Nano 328(Arduino compatible) can go with the IO Shield for Arduino Nano, it would be more friendly and convenient for users to enter the Arduino world and make use of Arduino to make their dream into reality.

    As an upgrade version of Arduino Nano, This Nano 328 is 100% compatible to Arduino Nano and its shield and IDEs. On the hardware part, remarkable changes are taken to improve the flexibility and user experience.


  • Power OK red LED, Green (TX), green (RX) and green (L) LED
  • Upgraded 5V voltage sourcing, more powerful drive capability
  • Mini-B USB for programming and serial monitor, TX&RX breakout for application as USB-UART convertor
  • Surface-Mount ICSP header
  • Standard 2.54mm spacing DIP (breadboard friendly)


  • Microcontroller: ATmega328
  • Operating Voltage(logic level): 5V
  • 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: 16 KB (ATmega168) or 32 KB (ATmega328) of which 2 KB used by bootloader
  • SRAM: 1 KB (ATmega168) or 2 KB (ATmega328)
  • EEPROM: 512 bytes (ATmega168) or 1 KB (ATmega328)
  • Clock Speed: 16 MHz
  • Dimension: 0.73" x 1.70"


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.

The FTDI FT232RL chip on the Nano is only powered if the board is being powered over USB. As a result, when running on external (non-USB) power, the 3.3V output (which is supplied by the FTDI chip) is not available and the RX and TX LEDs will flicker if digital pins 0 or 1 are high.


The ATmega168 has 16 KB of flash memory for storing code (of which 2 KB is used for the bootloader); the ATmega328 has 32 KB, (also with 2 KB used for the bootloader). The ATmega168 has 1 KB of SRAM and 512 bytes of EEPROM (which can be read and written with the EEPROM library); the ATmega328 has 2 KB of SRAM and 1 KB of EEPROM.

work great Review by Waldron
the quality is very good. after testing of my projects, it really Compatible arduino. After receive, I also did an experiment that quickly put all computers into the computer USB port, and run with different flashing rate three "flashing" program. And i found that everything work as expected. Then I will analog and digital I/O lines from one of the Mega 2560 transferred to Nanos, slightly modify the software, make me satisfied is that everything is running well, run on this tiny controller! I also strongly recommend this product. (Posted on 5/16/2017)
