This is a low-cost version of Arduino UNO compatible, using CH340 as USB to UART chip, you have more reasons kick start the digital making. And this UNO compatible board is fully compatible with Arduino UNO R3, yes R3. Basically, the changes that you might notice is the CH340 driver, which you can download and install from here: Windows, Mac OS, Linux (pre-installed). Other than that, everything is compatible, the shields and the sketches.

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 interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently support Mac OS X, Windows, and Linux).
