MEGA2560 MEGA 2560 R3 ATmega2560-ATMEGA16U2 AVR USB Board Development Board MEGA2560 for Arduino The Arduino MEGA2560 2012 R3 version is the latest version of the MEGA series arduino controller, which differs from the 2011 version as follows: 1. Replace the 2011 version of the ATMEGA8U2 with the ATMEGA16U2 chip. The ISP FLASH capacity is doubled for more powerful function expansion and development needs. In addition to the traditional USB to serial port function, ATMEGA16U2 allows users to program other functions, such as mouse, keyboard, joystick, camera, etc. Publish specific implementation plans. 2. The external interface adds SDA and SCL (located on the left side of AREF) based on the 2011 version. The IOREF interface can provide a voltage reference to the Shield. And for future series product compatibility, consider leaving a port on the left side of IOREF. 3. The RESET circuit is improved compared to the 2011 version. To prevent accidental reset of RESET, the RESET circuit is more stable. #MEGA2560 #ATmega2560 #ATMEGA16U2 #16U2 #R3
