Uno R3 Board based on Arduino


Arduino Uno R3 Board

This is the new Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations). This allows for faster transfer rates and more memory. No drivers are needed for Linux or Mac, and the ability to have the Uno show up as a keyboard, mouse, joystick, etc.

The Arduino Uno R3 is one of the more popular boards in the Arduino family and a great choice for beginners. The Arduino platform has become quite popular with people just starting out with electronics and programming, and for good reason. Unlike previous programmable circuit boards, the Arduino Uno R3 does not need a separate piece of hardware (called a programmer) in order to load new code onto the board – you can simply use a USB cable, and what’s more, there are plenty of online documents to help you solve your problem.

Other Variants of Arduino Board

For more advanced users, we do carry other Arduino Variants such as the Arduino Mega Board, which has a similar function to an Arduino Uno R3 but with more Input/Output (I/O) pins, or Arduino Nano, a compact version of the Arduino Uno R3 for those project with size constraints.

What makes the Arduino Uno R3 even more popular is the existence of Arduino shields, shields in general are boards that you place on top of the Arduino Uno Board for easier prototyping, without the hassle of using wires to connect each pin.

If you’re not sure on where to start we recommend the Arduino Starter Kit.

What is Arduino?

Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone projects or can be connected to software on your computer. The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux).
