One look at the Nano and Uno, and you can immediately tell how significantly different they are in terms of size. The Nano, just as its name suggests, is the smaller board between the two, and interestingly, also the tiniest ever produced by Arduino. It comes in a light seven-gram weight, with dimensions of 45 mm (length) by 18 mm (width). The Uno, on the other hand, is much bigger. It weighs more than three times the Nano at 25 grams and has a larger footprint, with a length of 68.6 mm and a width of 53.4 mm. With its ports, the Uno stands at a total height of 15.4 mm, although with all the I/O pins soldered on, the Nano is a little bit thicker at 18.6 mm.
When it comes to actual applications, this striking difference in size makes the boards ideal for separate types of projects. The small form factor of the Nano comes in handy for building portable and compact electronic projects, such as a smart IR thermometer, RGB goggles, and a universal TV remote. Meanwhile, the Uno is more suitable for general-purpose projects. As long as what you’re building doesn’t need to be squeezed into a tight case, you can likely use an Uno board for it. Some beginner-friendly Arduino Uno projects you can get started with include an ultrasonic piano, a gesture-controlled system for VLC, and an automatic plant watering device.
