Does this need external power or does it power through usb connection?? If external what power supply is recommended?

Hi, the answer is both - either - but not at the same time! When you are downloading a sketch, the USB powers things, but for remote running in a project, it will run off 7-12 volts into a jack. I have an old HDD psu that plugs into the mains and gives 12v at 1.5 amps, and that's fine. I hope this helps

can I use any usb cable for this? I can't find a cable that states it is compatible. Amazon's earch is no good. sort it out.

You will require a USB cable type 1,2 or 3 with the other end a USB type B plug as per the image shown of the Arduino board and the type B socket [upper left] on the Mega board in order to upload sketches. The lower black socket is for a standard 9V din plug. I'm not sure if the Amazon offer includes a cable or not, it does not make that clear.

is this an original arduino board?

The official Arduino website are selling the MEGA 2560 R3 at 35 euros (+ tax). They also have this information available free for you to assess whether the arduino you have is authentic. https://www.arduino.cc/en/Products/Counterfeit I cannot tell from the information you have posted, but it does seem about the same price as a genuine board.

Does this really have WiFi?

Hello, The board has an ATmega2560 which has 54 digital input/output connections (14 of which can be used as PWM outputs), 16 analog outputs, 4 UARTs, a 16 MHz processor, a USB connection, a power connection. Operating voltage 5V. Best regards, Lemona electronics
