    Everything works fine, only before work you need to set up jampers (switches on the board 1-8), it is necessary to select the processor and their operating modes (ATmega and ES Information on setting up is easy to find on the Internet. Can work as normal Arduino Mega 2560. With WiFi has not yet figured out, but apparently for it you need to connect the antenna. Everything is qualitatively and well done. But only the package needs better. And so I recommend!
