This Nano microcontroller (simply called "Nano") is a must-have for hobbyists and professionals alike. One of the most common microcontrollers, with endless online tutorials and examples. This Nano has 2 rows of 15 pins on a compact board. There are several analog and digital pins (see Technical Specifications below), as well as a USB B port interface. The USB port is supported by the common CH340 IC. Simply plug the Nano via USB into your computer and use the free Arduino IDE software to upload scripts (See our tutorial on first time using the Nano Microcontroller)

Other Resources

  • The Nano is one of our favorite microcontrollers and we use it in many of our projects that are not particularly orientated or focused on the Nano itself (for example NRF type projects). Please visit our Tutorials page to see the list of available tutorials. In terms of this product, consider the below entry-level tutorials for getting started with the Nano.
