ELEGOOO Mega R3 is an ATmega+2560 micro-controller board. It would be an intelligent choice of the board for 3D printers, robotics projects, and more other projects with 54 digital I/O pins (of which 15 can be used as PWM outputs), 16 analog inputs, and a larger space for your sketch. The ATmega+2560 on the Elegoo Mega comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. The ATmega+2560 of ELEGOO Mega R3 Controller Board has 256 KB of flash memory for storing code (of which 8 KB is used for the bootloader), 8 KB of Spram, and 4 KB of EEPROM (which can be read and written with the EEPROM library).
- The Mega is 100% compatible with Arduino IDE and most of the shields are designed for the Arduino Mega R3
- Besides the 54 digital I/O pins and 16 analog inputs, it also has 4 UARTs (hardware serial ports)
- The Mega R3 has a resettable fuse that protects your computer's USB ports from shorts and over-current.
- The ELEGOO Mega R3 can be powered via a USB connection or with an external power supply.
- The chip is Atmega + 2560-16au and 16u2, the same as the official version.
