This is RobotDyn's Arduino Uno compatible board. It's fully compatible with the original, with a few slight changes. The RobotDyn Uno has ditched the aging USB B connector for the now more common USB micro connector and broken out two additional analog pins, A6 and A.
Instead of the FTDI USB to serial converter chip, this board uses the CH340. If you don't already have it, you'll need to download and install the driver for it before your computer will detect it. You can find more information and download links in the first item on our FAQ page.
