This product is a cost effective version of the original Arduino Nano. The only difference being that the USB to Serial converter chip is the CH340 instead of the Atmega16U2 FTDI chip.

As the name would suggest, this Nano Board is a more compact board, designed to provide very similar functionality to the Arduino UNO and Duemilanove – only in a smaller, more space-efficient package. It utilizes a mini USB connector, compared to the standard size, and doesn’t require an external power source. Rather, the efficient design allows for the single connector to simultaneously provide power, as well as access to the microcontroller.

Based on the ATmega328 microcontroller, the breadboard-friendly Nano Board offers a total of 14 digital I/O channels, 6 of which are PWM I/O, as well as 8 analog inputs. The board runs at 16 MHz clock speed and utilizes 32kB of flash memory – with 2KB reserved for operating the bootloader.

The primary difference when comparing the Nano to the UNO is that the Nano offers two extra I/O pins, a higher clock speed and better storage space. Additionally, while the UNO was designed for beginners to easily learn and utilize, the Nano is more suited to advanced users.

*Note* If you are still using the Windows 7 operating system you will need to manually download the driver for the CH340 chip for your PC to recognise and communicate with this board.
