* Programming - The Arduino/Genuino Uno can be programmed with the (Arduino Software (IDE)). * Warnings - The Arduino/Genuino Uno has a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent. * Differences with other boards - The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. * Power - The Arduino/Genuino Uno board can be powered via the USB connection or with an external power supply. * Memory - The ATmega328 has 32 KB (with 0.5 KB occupied by the bootloader). It also has 2 KB of SRAM and 1 KB of EEPROM (which can be read and written with the EEPROM library). * Input and Output - See the mapping between Arduino pins and ATmega328P ports. The mapping for the Atmega8, 168, and 328 is identical. * Communication - Arduino/Genuino Uno has a number of facilities for communicating with a computer, another Arduino/Genuino board, or other microcontrollers. * Automatic (Software) Reset - Rather than requiring a physical press of the reset button before an upload, the Arduino/Genuino Uno board is designed in a way that allows it to be reset by software running on a connected computer.

* Nanode provides the same Arduino shield connectors allowing the system to be expanded by stacking boards on top. When using shields for expansion, you have to be aware that not all shields are fully compatible because of the on-board hardware utilisations mentioned above. * Nanode is produced as a build it yourself kit using conventional through-hole components. This is to encourage people to engage in the rewarding experience of building their own electronic devices and have a go at creating new and fascinating projects. Nanode is fully open source and all of the design documentation may be accessed from this site.
