Everything comes from China products reviews site purchased in China
After using the Arduino Uno, I thought I'd explore the Mega model the series, that has a lot more exits and entrances.
Comes with the cable and the. This is not an official version of Arduino, but it works with the Official IDE without problem.
In addition to having more input and output ports the Mega model also features more Flash memory, EEPROM and SRAM.
The model must be compatible with all shields and libraries of Uno. Although anything can stop working.
The interface is USB as in UNO.
This Mega version is almost the same price of UNO version, and has more options for use. I think it's worth buying the two, because there's a lot more to support Uno model on the internet. I leave the link to both:
UNO – http://www.dx.com/p/uno-r3-atmega328p-uno-r3-development-board-deep-blue-285620
the problem and make the mega 2560 recognize the USB port and record
Look for Chinese drivers for Arduino (USB FTDI). Usually this is the problem.
