Arduino has decided to further develop its catchy Nano project in the direction of more power. Nano Every is the simplest of the new series as it doesn´t include any sensors nor connectivity solution, however still significantly more powerful than standard Nano (50% more program memory and 2 times more RAM). Above characteristics make it perfect for projects of small devices with more advanced functionalities, such as audio processing or robotics.
