Funduino MEGA2560 R3 is MEGA series and 2011 2012 version of the difference is as follows:
1. Use ATMEGA16U2 chip instead of the 2011 version ATMEGA8U2, ISP FLASH capacity doubled, facilitate more powerful function expansion, development needs. ATMEGA16U2 turn in addition to providing traditional USB serial port function, can also allow the user to define their programming other functions, such as USB port can be configured to the mouse, keyboard, game rocker, camera and so on, of course, these applications are yet to be released the Arduino team specific implementation plan.
2. The external interface based on the 2011 version increased the SDA and SCL (position in the top left of the AREF). IOREF interface can be provided to shields a voltage reference. And a series of products for the future compatibility consider IOREF a port on the left side of the reserve.
3. RESET circuit version improved than in 2011. Prevent accidental RESET RESET, RESET circuit is more stable.
