This a generic low-cost arduino R3 SMD version clone with the USB cable included. The only difference is the USB-Serial chip is a CH340 and not an ATMEL 16u2.
If you are buying an Arduino for the first time: BUY THE ORIGINAL!
If the generic version scares you: BUY THE ORIGINAL!
If you have any doubts whatsoever, please: BUY THE ORIGINAL!
