Technical Specifications of Arduino NanoĪs Arduino Nano is also based on ATmega328P Microcontroller, the technical specifications are similar to that of UNO. Regarding the pin, I will discuss about them in the Arduino Nano Pinout Section. Apart from that, the layout of Arduino Nano is very much self-explanatory. Also, there is no 2.1 mm DC jack to provide external power supply. As you can see from the previous image, there are a couple of components on the bottom side of the board as well (5V Regulator and USB-to-Serial Converter IC are the main ones).Īs you can notice, the Type-B USB connector from Arduino UNO is replaced with mini-B type connector. The following image shows the layout of a typical Arduino nano board. Personally speaking, I suggest Arduino Nano over UNO as it is cheaper, breadboard friendly, small in size and has couple of more pins (digital and analog IO) than UNO. Overall, the Arduino Nano is a very good alternative to the mighty Arduino UNO and is available at a lower price. The Nano board is designed in such a way that the pins are breadboard friendly so that you can easily mount it on one for your DIY projects.
Other than that Nano is very similar to UNO in terms of functionality. If you compare UNO and Nano, then Nano lacks the DC Power Jack and contains a mini-B type USB connector. Despite the size, Arduino Nano packs in more or less the same features as UNO.
