Description

Arduino Nano CH340 has a lower cost USB-Serial Chip that makes it less in price than the Arduino.

The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.

Arduino Nano can be powered via mini-USB connector, 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.

Comparison with Arduino UNO:

  • Digital IOs: Arduino Nano and Arduino UNO have exactly same number of Digital IOs (i.e. 14)
  • PWM Channels: Arduino Nano and Arduino UNO have exactly same numbers of PWM Channels (i.e. 6)
  • Clock: Arduino Nano and Arduino UNO have exactly same clock frequency (16.000 MHZ)
  • Flash Memory:  Arduino Nano and Arduino UNO have exactly same amount of flash Memory (i.e. 32KB)
  • Data Memory:  Arduino Nano and Arduino UNO have exactly same amount of Data Memory / RAM (i.e. 2KB)
  • EEPROM Memory:  Arduino Nano and Arduino UNO have exactly same amount of EEPROM Memory / RAM (i.e. 1KB)

Features:

  • Automatic reset during program download
  • Power OK blue LED on the bottom
  • Green (TX), red (RX) and orange (L) LED
  • +5V to AREF jumper
  • Auto sensing/switching power input
  • Small mini-B USB for programming and serial monitor (cable not included)
  • ICSP header for direct program download
  • Power OK blue LED on the bottom
  • Standard 0.1” spacing DIP (breadboard friendly)
  • Manual reset switch
