Product detailed description

The most legendary Arduino board on the market. Thanks to its popularity, versatility, and community, the Arduino Uno rev3 is an ideal board for both beginners and advanced users. It offers an excellent price/performance ratio and a huge amount of available shields and extensions.

Thanks to the ATmega16U2 converter and integrated USB connector, you can upload a program to the board without external electronics. The ATmega328P microcontroller is mounted in a socket in the board and can therefore be used in your own construction. The board also offers a standard coaxial power connector, which can be used to power the board, for example from a battery or a mains adapter. On the software side, the board is programmed via the integrated Arduino IDE development environment.

This board is suitable for both beginners and advanced hobbyists, and thanks to its versatility and extensive documentation, it can be used in almost any project.

Vše proběhlo rychle a v pořádku. Mám jen jeden problém. V objednávce sem měl i CNC shield se čtyřmi driver. A problém je že u jednoho driveru chybí hliníkový chladič proto dávám o hvězdičku méně.
