Make sure this fits by entering your model number.
ELEGOO Mega R3 board is 100% compatible with Arduino IDE and designed for Mega R3 Kit Project
ELEGOO Mega R3 board use the controller chip
Improved and expert version: 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Due that operate with 3.3V. The second one is a not connected pin, that is reserved for future purposes.
ELEGOO Mega R3 uses stronger RESET circuit as to offer better function experience
This Mega R3 board contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.
