The MEGA2560 R3 also adds SDA and SCL pins next to the AREF. In addition, there are two new
pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage
provided from the board. The other is a not connected and is reserved for future purposes. The
MEGA2560 R3 works with all existing shields but can adapt to new shields which use these
additional pins.
